mp3info2 - get/set MP3 tags; uses MP3::Tag to get default values.



  # Print the information in tags and autodeduced info
  mp3info2 *.mp3

  # In addition, set the year field to 1981
  mp3info2 -y 1981 *.mp3

  # Same without printout of info, recursively in the current directory
  mp3info2 -R -p "" -y 1981 .

  # Do not deduce any field, print (normalized) info from the tags only
  mp3info2 -C autoinfo=ID3v2,ID3v1 *.mp3

  # As above, but without normalization/autofill, the raw information in tags
  mp3info2 -N *.mp3

  # As above, but only with ID2v1 tag read
  mp3info2 -NC autoinfo=ID3v1 *.mp3

  # Get artist from CDDB_File, autodeduce other info, write it to tags
  mp3info2 -C artist=CDDB_File -u *.mp3

  # For title, prefer information from .inf file; autodeduce rest, update
  mp3info2 -C title=Inf,ID3v2,ID3v1,filename -u *.mp3

  # Same, and get the artist from CDDB file
  mp3info2 -C title=Inf,ID3v2,ID3v1,filename -C artist=CDDB_File -u *.mp3

  # Write a script for conversion of .wav to .mp3, autodeducing tags
  mp3info2 -p "lame -h --vbr-new --tt %t --tn %n --ta %a --tc %c --tl %l --ty %y %f\n" *.wav >


The program prints a message summarizing tag info (obtained via MP3::Tag module) for specified files.

It may also update the information in ID3 tags. This happens in three different cases.
o If the information supplied in command-line options t a l y g c n differs from the content of the corresponding ID3 tags (or there is no corresponding ID3 tags).
o If options -d or -F were given.
o if MP3::Tag obtains the info from other means than MP3 tags, and -u forces the update of the ID3 tags.
(All these ways are disabled by -D option.) ID3v2 tag is written if needed, or if -2 option is given. (Automatic fill-in of deduceable fields (via the method id3v2_frames_autofill()) is performed unless -d or -N options are given.)

The option -u writes (updates) the fetched information to the MP3 ID3 tags. This option is assumed if there are command-line options which explicitly set tag elements (-a, -t etc., and -F, -d). (Effects of this option may be overridden by giving -D option.) If -2 option is also given, forces write of ID3v2 tag even if the info fits the ID3v1 tag (in addition, this option enables auto-update of personal name fields, and corresponding titles according to values of translate_person, person_frames etc. configuration settings; see Normalization of fields). This option is ignored if no change to tags is detected; however, one can force an update by repeating this option (useful if you expect the change the format of the tag, as opposed to its content).

The option -p prints a message using the next argument as format (by default \\, \t, \n are replaced by backslash, tab and newline; governed by the value of -E option); see interpolate in MP3::Tag for details of the format of sprintf()-like escapes. If no option -p is given, message in default format will be emitted. The value of option -e is the encoding used for the output; if the value is a number, system-specific encoding is guessed (and used for the output if bit 0x1 is set); if bit 0x2 is set, then, command line options are assumed to be in the guessed encoding; if bit 0x4 is set, then, command line arguments are assumed to be in the guessed encoding. Use the value binary to do binary output.

With option -D (dry run) no update is performed, no matter what the other options are. With this option, no parsing of tags is performed unless needed.

Use options

  t a l y g c n

to overwrite the information (title artist album year genre comment track-number) obtained via MP3::Tag heuristics (-u switch is implied if any one of these arguments differs from what would be found otherwise; use -D switch to disable auto-update). By default, the values of these options are not %-interpolated; this may be changed by -E option.

The option -d should contain the comma-separated list of ID3v2 frames to delete. A frame specification is the same as what might be given to "%{...}" frame interpolation command, e.g., TIT3, COMM03, COMM(fra)[short title]; the difference with modify-access is that <B>ALLB> (and not the <B>firstB> of) matching frames are deleted. (Option -d may be repeated.)

For example, -d APIC would remove all picture frames. In addition, if the list contains ID3v1 or ID3v2, whole tags will be deleted.

Likewise, the option -F allows setting of arbitrary ID3v2 frames: if one needs to set one frame, use the directive FRAME_spec=VALUE:

  -F TIT2=The_new_Title

Again, on modify, <B>ALLB> matching frames are deleted first, so be carefull with

  -F COMM=MyComment

Option -F may be repeated to set more than one frame. If configuration variable empty-F-deletes is TRUE (default), empty arguments will delete the frame.

One can replace FRAME_spec=VALUE by FRAME_spec < FILE; in this case the value to set is read from the file named FILE; if the frame is text-only (meaning: at most [encoded]Text URL Language Description fields are present), the file is read in text mode (and with starting/trailing whitespace stripped), otherwise it is read in binary mode. (Whitespace is required about the < signs.) If < is replaced by ?<, the value is set only if frame is not yet present, and if the file exists; if replaced by >, the value (if present) is written to FILE (creation of intermediate directories is controlled by configuration option frames_write_creates_dirs, the default is FALSE).

Additionally, FRAME_spec may be one of ID3v1 or ID3v2 or TAGS; in this case, whole tags are written or read. For example, for TAGS < FILE, title artist album year genre comment track info is calculated from FILE, which may be raw tags, as produced with >, or a valid MP3 file; if Image::ExifTool is present, the data may be read from arbitrary multimedia file. (Likewise, for ID3v1 < FILE, the same info is extracted from ID3v1 tag only.) After this, in case of ID3v2 or TAGS, ID3v2 frames are copied from the ID3v2 tag one-by-one. (With suitable modifications for ?<.)

By default, the VALUE for -F is %-interpolated; this can be changed by option -E. For user convenience, human-friendlier forms composer, text_by, orchestra, conductor, disk_n can be used instead of TCOM, TEXT, TPE2, TPE3, TPOS.

The option -P RECIPE is a very powerful generalization of what can be done by options -F, -d, and -t -a -l -y -g -c -n. It may be repeated; the values should contain the parse recipes. They become the configuration item parse_data of MP3::Tag; eventually this information is processed by MP3::Tag::ParseData module (if the latter is present in the chain of heuristics; see option -C). The RECIPE is split into $flags, $string, @patterns on its first non-alphanumeric character; the first of @patterns which matches $string is going to be executed (for side effects). (See examples: EXAMPLES: parse rules.)

If option -G is specified, the file names on the command line are considered as glob patterns. This may be useful if the maximal command-line length is too low. With the option -R arguments can be directories, which are searched recursively for audio (default *.mp3) files to process; use option -r to reset the regular expression to look for (the default is (?i:\.mp3$)).

The option -E controls expansion of escape characters. It should contain the letters of the command-line options where \\, \n, \t are interpolated; one can append the letters of t a l y g c n F options requiring %-interpolation after the separator /i: (for -F, only the values are interpolated). The default value is p/i:Fp: only -p is \-interpolated, and only -F and -p are subject to %-interpolation. If all one wants is to add to the defaults, preceed the value of -E (containing added options) by "+". (Some parts of the value of option -P are interpolated, but this should be governed by flags, not -E; do NOT put P into the %-interpolated part of -E.)

If the option -@ is given, all characters @ in the options are replaced by %. This may be convenient if the shell treats % specially (e.g., DOSISH shells).

If option -I is given, no guessworking for artist field is performed on typeout.

The option -C CONFIG_OPT=VALUE1,VALUE2... sets MP3::Tag configuration data the same way as MP3::Tag-config()> would do (recall that the value is an array; separate elements by commas if more than one). The option may be repeated to set more than one value. Note that since ParseData is used to process -P parse recipes, it should be better be kept in the autoinfo configuration (and related fields author etc) in presence of -P.

If the option -x is given, the technical information about the audio file is printed (MP3 level, duration, number of frames, padding, copyright, and the list of ID3v2 frame names in format suitable to %{...} escapes). If -x is repeated, content of frames is also printed out (may output non-printable chars, if it is repeated more than twice).

If option -N is given, all the smarts are disabled - no normalization of fields happens, and (by default) no attempt to deduce the values of fields from non-ID3 information is done. This option is (currently) equivalent to having -C autoinfo=ParseData,ID3v2,ID3v1 as the first directive, to having no present on @INC path, and not calling autofill() method.

Normalization of fields

(The loading of normalization module and all subsequent operations may be disabled by the option -N, or by setting the environment variable MP3TAG_NORMALIZE_FIELDS to be FALSE. If not prohibited, the module is attempted to be loaded if directory ~/.music_fields is present, or MP3TAG_NORMALIZE_FIELDS is set and TRUE.)

If loading of the module Normalize::Text::Music_Fields is successful, the following is applicable:

If the value of MP3TAG_NORMALIZE_FIELDS is defined and not 1, this value is broken into directories as a PATH, and load path of Normalize::Text::Music_Fields is set to be this list of directories. Then MP3::Tag is instructed (via corresponding configuration settings) to use normalize_artist (etc.) methods defined by this module. These methods may normalize certain tag data. The current version defines methods for normalization of personal names, and titles (based on the composer). This normalization is driven through user-editable configuration tables.

In addition to automatical normalization of MP3 tag data, one can use fake MP3 files to manually access some features of this module. For this, use an empty file name, and -D option. E.g,

  mp3info2 -D -a beethoven                       -p "%a\n"         ""
  mp3info2 -D -a beethoven                       -p "%{shP[%a]}\n" ""
  mp3info2 -D -a beethoven -t "sonata #28"       -p "%t\n"         ""
  mp3info2 -D -a beethoven -t "allegretto, Bes" -@p "@t\n"         ""
  mp3info2 -D -a beethoven -t "op93"            -@p "@t\n"         ""

will print the normalized person-name for beethoven, the corresponding normalized short person-name, and the normalized title for sonata #28 of composer beethoven. E.g., with the shipped normalization tables, it will print

  Ludwig van Beethoven (1770-1827)
  L. van Beethoven
  Piano Sonata No. 28 in A major; Op. 101 (1816)
  Allegretto for Piano Trio in B flat major; WoO 39 (1812)
  Symphony No. 8 in F major; Op. 93 (comp. 1812, f.p. Vienna, 1814-02-27, cond. Beethoven; pubd. 1816)

The order of operation

Currently, the operations are done in the following order
o Deletion of ID3v1 or ID3v2 as a whole via -d option;
o Recipies of -P option are set up (to be triggered by interpolation);
o The setting done via -a/-t/-l/-y/-g/-c/-n options;
o The settings done via -F option;
o Deletion of individual frames via -d option;
o autofill of ID3v2 (id) frames;
o Emit info based on -p and -x options;
o Trigger recipies of -P (if not triggered by interpolation);
o Update tags if needed.

Usage strategy: escalation of complexity

The purpose of this script is to to make handling of ID3 tags as simple as possible.

On one end of the scale, one can perform arbitrarily complex manipulations with tags using MP3::Tag Perl module.

On the other end, it is much more convenient to handle simplest manipulations with tags using this script’s options -t -a -l -y -g -c -n and -p -F -d. For slightly more complicated tasks, one may need to use the more elaborate method of parse rules, provided to this script by the option -P; the rules depend heavily on interpolation, see interpolate in MP3::Tag, interpolate_with_flags in MP3::Tag.

To simplify upgrade from simplest manipulations to more elaborate ones, here we provide parse rule synonyms to the simplest options. So if you start with -t -a -l -y -g -c -n and -p -F -d options which almost work for you, you have a good chance to be able to fully achieve your aim by modifying the synonyms described below.

(Below we assume that -E option is set to its default value, so -F -p are %-interpolated, other options are not. Note also that if your TTY’s encoding is recognized by Perl, it is highly recommended to set -e 3 option; on DOSISH shells, better use -@, and replace %’s by @’s below.)

  -P "mz/VALUE/%t"

-a -l -y -g -c -n Likewise.

  -P "mzi/VALUE/%{TIT2}"

-F ‘‘APIC[myDescr] < FILE’’

  -F "APIC[myDescr]=%{I(fimbB)FILE}"


  -P "mzi/%{I(fimbB)FILE}/%{APIC[myDescr]}"

(remove bB for text-only frames).

-F ‘‘APIC[myDescr] > FILE’’

  -P "bOi,%{APIC[myDescr]},FILE"

(remove b for text-only frames); or use -e binary -p "%{APIC[myDescr]}" with redirection, see EXAMPLES: parse rules.

-d TIT2

  -P "m//%{TIT2}"

-F ‘‘TIT2 ?< FILE’’ Very tricky. This won’t set distinguish empty file and non-existing one:

  -P "mzi/%{TIT2:1}0%{I(fFim)FILE}/10/10%{TIT2}/0%{U1}"

(add bB to fFim for non-text-only frames); the last part may be omitted if one omits the flag m - it is present to catch misprints only.

For details on parse rules, see EXAMPLES: parse rules and DESCRIPTION in MP3::Tag::ParseData.

EXAMPLES: parse rules

Only the -P option is complicated enough to deserve comments... For full details on parse rules, see DESCRIPTION in MP3::Tag::ParseData; for full details on interpolation, see interpolate in MP3::Tag, interpolate_with_flags in MP3::Tag.

For a (silly) example, one can replace -a Homer -t Iliad by

  -P mz=Homer=%a -P mz=Iliad=%t

A less silly example is forcing a particular way of parsing a file name via

  -P "im=%{d0}/%f=%a/%n %t.%e"

It is broken into

 flags          string          pattern1
 "im"           "%{d0}/%f"      "%a/%n %t.%e"

The flag letters stand for interpolate, must_match. This interpolates the string "%{d0}/%f" and parses the result (which is the file name with one level of the directory part preserved) using the given pattern; thus the directory name becomes the artist, the leading numeric part - the track number, and the rest of the file name (without extension) - the title. Note that since multiple patterns are allowed, one can similarly allow for multiple formats of the names, e.g.

  -P "im=%{d0}/%f=%a/%n %t.%e=%a/%t (%y).%e"

allows for the file basename to be also of the form TITLE (YEAR). An alternative way to obtain the same results is

  -P "im=%{d0}=%a" -P "im=%f=%n %t.%e=%t (%y).%e"

which corresponds to two recipies:

 flags          string          pattern1        pattern2
 "im"           "%{d0}"         "%a"
 "im"           "%f"            "%n %t.%e"      "%t (%y).%e"

Of course, one could use

 "im"           "%B"            "%n %t"         "%t (%y)"

as a replacement for the second one.

Note that it may be more readable to set artist to %{d0} by an explicit asignment, with arguments similar to

  -E "p/i:Fpa" -a "%{d0}"

(this value of -E requests %-interpolation of the option -a in addition to the default \-interpolation of -p, and %-interpolation of -F and -p; one can shortcut it with -E +/i:a).

To give more examples,

  -P "if=%D/.comment=%c"

will read comment from the file .comment in the directory of the audio file;

  -P "ifn=%D/.comment=%c"

has similar effect if the file .comment has one-line comments, one per track (this assumes the the track number can be found by other means).

Suppose that a file Parts in a directory of MP3 files has the following format: it has a preamble, then has a short paragraph of information per audio file, preceded by the track number and dot:


   12. Rezitativ.
   (Pizarro, Rocco)

   13. Duett: jetzt, Alter, jetzt hat es Eile, (Pizarro, Rocco)


The following command puts this info into the title of the ID3 tag (provided the audio file names are informative enough so that MP3::Tag can deduce the track number):

 mp3info2 -u -C parse_split=\n(?=\d+\.) -P fl;Parts;%=n. %t

If this paragraph of information has the form TITLE (COMMENT) with the COMMENT part being optional, then use

 mp3info2 -u -C parse_split=\n(?=\d+\.) -P fl;Parts;%=n. %t (%c);%=n. %t

If you want to remove a dot or a comma got into the end of the title, use

 mp3info2 -u -C parse_split=\n(?=\d+\.) \
   -P fl;Parts;%=n. %t (%c);%=n. %t -P iR;%t;%t[.,]$

The second pattern of this invocation is converted to

  [iR, %t => %t[.,]$]

which essentially applies the substitution s/(.*)[.,]$/$1/s to the title.

Now suppose that in addition to Parts, we have a text file Comment with additional info; we want to put this info into the comment field after what is extracted from TITLE (COMMENT); separate these two parts of the comment by an empty line:

 mp3info2 -E C -C parse_split=\n(?=\d+\.) -C parse_join=\n\n \
  -P f;Comment;%c           -P fl;Parts;%=n. %t              \
  -P i;%t///%c;%t (%c)///%c -P iR;%t;%t[.,]$

This assumes that the title and the comment do not contain /// as a substring. Explanation: the first pattern of -P,

  [f, Comment => %c],

reads comment from the file Comment into the comment field; the second,

  [fl, Parts  => %=n. %t],

reads a chunk of Parts into the title field. The third one

  [i, %t///%c => %t (%c)///%c]

rearranges the title and comment provided the title is of the form TITLE (COMMENT). (The configuration option parse_join takes care of separating two chunks of comment corresponding to two occurences of %c on the right hand side.)

Finally, the fourth pattern is the same as in the preceding example; it removes spurious punctuation at the end of the title.

More examples: removing string with violin from the start of the comment field (removing comment altogether if nothing remains):

  mp3info2 -u -P iz;%c;with violin%c *.mp3

setting the artist field without letting auto-update feature deduce other fields from other sources;

  mp3info2 -C autoinfo=ParseData -a "A. U. Thor" *.mp3

setting a comment field unless it it already present:

  mp3info2 -u -P i;%c///with piano;///%c *.mp3

The last example shows how to actually write programs in the language of the -P option: the example gives a conditional assignment. With user variables (as in %{U8}) for temporaries, and a possibility to use regular expressions, one could provide arbitrary programmatic logic. Of course, at some level of complexity one should better switch to direct interfacing with MP3::Tag Perl module (use the code of this Perl script as an example!).

Here is a typical task setting advanced id3v2 frames: composer (TCOM), orchestra (TPE2), conductor (TPE3). We assume a directory tree which contains MP3 files tagged with the following conventions: artist is actually a composer; comment is of one of two forms:

  Performers; Orchestra; Conductor
  Orchestra; Conductor

To set the specific MP3 frames via -P rules, use

  mp3info2 -@P "mi/@a/@{TCOM}" \
    -P "mi/@c/@{U1}; @{TPE2}; @{TPE3}/@{TPE2}; @{TPE3}" -R .

With -F options, this can be simplified as

  mp3info2 -@F "TCOM=@a" -P "mi/@c/@{U1}; @{TPE2}; @{TPE3}/@{TPE2}; @{TPE3}" -R .


  mp3info2 -@F "composer=@a" -P "mi/@c/@{U1}; @{TPE2}; @{TPE3}/@{TPE2}; @{TPE3}" -R .

To copy ID3 tags of MP3 files in the current directory to files in directory /tmp/mp3 with the extension .tag (and print progress report), use

  mp3info2 -p "@N@E\n" -@P "bODi,@{ID3v2}@{ID3v1},/tmp/mp3/@N.tag" -DNR .

Since we did not use z flag, MP3 files without tags are skipped.

Now suppose that there are two parallel file hierarchies of audio files, and of lyrics: audio files are in audio/dir_name/audio_name.mp3 with corresponding lyrics file in text/dir_name/audio_name.mp3. To attach lyrics to MP3 files (in COMM frame with description lyrics in language eng - this is a non-standard location, see below!), call

  mp3info2 -@P "fim;../text/@{d0}/@B.txt;@{COMM(eng)[lyrics]}" -Ru .

inside the directory audio. (Change fim to Ffim to ignore the audio files for which the corresponding text file does not exist.) (Of course, to follow the specifications, one should have used the field "%{USLT(eng)[]}" instead of "%{COMM(eng)[lyrics]}"; see below for variations).

Finish by a very simple example: all what the pattern

  -P i;%t;%t

does is removal of trailing and leading blanks from the title (which is deduced by other means).

More examples

With -F option, one could set the USLT frame as

  mp3info2 -@F "USLT(eng)[] < ../text/@{d0}/@B.txt" -Ru .

Print out such a frame (in any language) with

  mp3info2 -@p "@{USLT[]}\n" file.mp3

Similarly, to print out the APIC frame with empty description, use

  mp3info2 -e binary -@p "@{APIC[]}" file.mp3 > output_picture_file

or (with description cover)

  mp3info2 -@P "bOi,@{APIC[cover]},output_picture_file.jpg" audio_07.mp3

To set such a frame from file xxx.gif (with the default Picture Type, "Cover (front)", and empty description), do one of

  mp3info2 -F  "APIC  <          xxx.gif"  file.mp3
  mp3info2 -@F "APIC[]=@{I(fimbB)xxx.gif}" file.mp3

The difference of APIC and APIC[] is that the first removes all APIC frames first, and the second removes only all APIC frames with empty description - but arbitrary image type. So it may be more suitable to use the full specification, as in APIC(Cover (front))[].

To remove APIC frames with empty descriptions, arbitrary Picture Types (and MIME types which may be correctly calculated by mp3info2, e.g., TIFF/JPEG/GIF/PNG), use

  mp3info2 -d "APIC[]" file.mp3

(note that this wouldn’t free disk space, unless shrink is forced by configuration variables). To do the same with the Conductor picture type only, do

  mp3info2 -d "APIC(Conductor)[]" file.mp3

To scan through subdirectories, and add file cover.jpg from the directory of the file as a default APIC frame, but only if there is no APIC frame, and a file exists, do

  mp3info2 -@F "APIC ?< @D/cover.jpg" -R .

This deletes empty frames for date, TCOP, TENC, WXXX[], COMM(eng)[], and removes the leading 0 from track number from MP3 file in current directory:

  mp3info2 -@ -E +/i:y -F "TCOP=@{TCOP}" -F "TENC=@{TENC}"
    -F "WXXX[]=@{WXXX[]}" -F "COMM(eng)[]=@{COMM(eng)[]}"
    -y "@y" -P "mi/@n/0@n/@n" *.mp3

Examples on dealing with broken encodings

One of principal weaknesses of ID3 specification was that it required that data is provided in latin-1 encoding. Since most languages in the world are not expressible in latin-1, this lead to (majority?) of ID3 tags being not standard-conforming. Newer versions of the specs fixed this shortcoming, but the damage was already done. Fortunately, this script can use abilities of MP3::Tag to convert from non-conforming content to a conforming one.

The following example converts ID3v2 tags which were written in (non-standard-conforming) encoding cp1251 to be in standard-conforming encoding. For the purpose of this example, assume that ID3v1 tags are in the same encoding (and that one wants to leave them in the encoding cp1251); the files to process are found in the current directory and (recursively) in its subdirectories (set syntax for DOSISH shells):

  mp3info2 -C id3v2_fix_encoding_on_write=1 -u2R .

For more information, see ENVIRONMENT in MP3::Tag, config in MP3::Tag, and CUSTOMIZATION in MP3::Tag.


This tool is loosely modeled on the program mp3info; it is mostly backward compatible (especially when in naive mode via -N), and allows a very significant superset of functionality. Known backward incompatibilities are:

  -G -h -r -d -x

Missing functionality:

  -f -F -i

Incompatible %-escapes:

  %e %E         - absolutely different semantic
  %v            - has no trailing 0s
  %q            - has fractional part
  %r            - is a number, not a word "Variable" for VBR
  %u            - is one less (in presence of descriptor frame only?)

Missing %-escapes:

  %b %G

Backslash escapes: only \\, \n, \t supported.

-x prints data in a different format, not all fields are present, and ID3v2 tag names are output.


With -e 1, 2 or 3, this script may consult environment variables LC_CTYPE, LC_ALL, LANG to deduce the current encoding. No other environment variables are directly read by this script.

Note however, that MP3::Tag module has a rich set of defaults for encoding settings settable by environment variables; see ENVIRONMENT in MP3::Tag. So these variables affect (indirectly) how this script works.


If you do not understand what it is about, it is safe to ignore this announcement:

The old, pre-version=1.05 way (by triplication of a separator, without repetition of options) to provide multiple commands to -F and <-P> options is still supported, but is strongly discouraged. (It does not conflict with the current interface.)

Utilities to create CDDB file

Good CD reapers (e.g., cdda2wav with option cddb=0) create a CDDB file with fetched information - as far as an Internet connection is present. However, if not available, other options exist.

The scripts (supplied with the distribution in ./examples) can create a stub CDDB file basing on: a dump of a full TOC of a CD; create one, e.g., by

  readcd -fulltoc dev=0,1,0 -f=audiocd directory of *.inf files (e.g., created by cdda2wav without Internet connection); a directory of MP3 files ripped from a CD (via some guesswork).
Passing this stub to the script, it can be transformed to a filled CDDB file via a connection to some online database. Use -r option if multiple records in the database match the CD signature.

  fulltoc2fake_cddb audiocd.toc | cddb2cddb     > audio.cddb
  inf_2fake_cddb                | cddb2cddb     > audio.cddb
  dir_mp3_2fake_cddb            | cddb2cddb -r3 > audio.cddb # 3rd record

When such a CDDB file is present, it will be used by MP3::Tag module to deduce the information about an audio file. This information is (by default, transparently) used by this script.
