Manual Reference Pages - PERL.REQ (1)
perl.req - list requirements for Perl scripts and libraries
<B>perl.reqB> calculates prerequisites for each Perl source file
specified on a command line; alternatively, a list of files is obtained
from standard input, one file per line. use, require and do
statements are processed. The output of perl.req is suitable for
automatic dependency tracking (e.g. for RPM packaging).
For example, /usr/lib/perl5/File/Temp.pm requires, in particular,
perl(Fcntl.pm) >= 1.030 (as of perl-5.8.6).
<B>perl.reqB> is basically a wrapper for B::PerlReq Perl compiler backend.
Use particular method for dependency tracking. Alternatively,
RPM_PERL_REQ_METHOD environement variable can be used to set the method.
The following methods are available:
Search thoroughly and list all requirements. In particular, list
platform-specific (non-UNIX) requirements and requirements found inside
Enable moderate search most acceptable for RPM packaging. That is,
skip files known to be platform-specific; skip platform-specific
requirements and those found inside eval blocks; skip most common
requirements (e.g. strict.pm).
Enable relaxed mode. That is, tolerate B::PerlReq failures; in addition
to normal method, skip conditional requirements (e.g. require
statements inside subroutines); skip do FILE statements; list only

Initial version of perl.req (part of RPM 3.0) done by Ken Estes
in 1999. Regular expressions were used to extract dependencies.
(Later a part of ALT Linux Master 2.0, with modifications from Mikhail
Reworked in November 2002: complicated regular expressions were added to
enhance search; methods added. (Later a part of ALT Linux Master 2.2.)
Reworked in September 2003: B::Deparse was utilized to re-format Perl
code before dependency extraction; hence more simple and accurate.
Decoupled from rpm-build package into rpm-build-perl. (Later a part of
ALT Linux Master 2.4.)
Reworked in December 2004: B::PerlReq was developed. Released on
CPAN, see <http://search.cpan.org/dist/rpm-build-perl/>.
