|-n DBFILE [SIZE]||This creates a new database. Currently, databases cannot be resized; you can choose a larger initial size if desired. The default size is 32,749.|
|-a DBFILE JARFILE LIB|
|-f DBFILE JARFILE LIB||This adds a jar file to the database. For each class file in the jar, a cryptographic signature of the bytecode representation of the class is recorded in the database. At runtime, a class is looked up by its signature and the compiled form of the class is looked for in the corresponding shared library. The -a option will verify that LIB exists before adding it to the database; -f skips this check.|
|[-][-0] -m DBFILE DBFILE,[DBFILE]||
Merge a number of databases. The output database overwrites any
existing database. To add databases into an existing database,
include the destination in the list of sources.
If - or -0 are used, the list of files to read is taken from standard input instead of the command line. For -0, Input filenames are terminated by a null character instead of by whitespace. Useful when arguments might contain white space. The GNU find -print0 option produces input suitable for this mode.
|-t DBFILE||Test a database.|
|-l DBFILE||List the contents of a database.|
|-p||Print the name of the default database. If there is no default database, this prints a blank line. If LIBDIR is specified, use it instead of the default library directory component of the database name.|
|--help||Print a help message, then exit.|
|-v||Print version information, then exit.|
