$my_name:
This command is a part of revbump package and intended for pkgsrc developers.
(1) Read entire pkgsrc tree and check referer -> referenced relation,
then internally keeps (opposite) referenced -> referer relation table.
(2) Read another file, named '$TABLE' or other name with -T, which
usually lists Makefile.common or *common.mk files to expand.
(3) Now expands those list in '$TABLE' into list of Makefiles by
referenced -> refer relation. By default, it outputs to the file
'$replaced' (currently the name is fixed).
Synopsys:
$my_name [-a ] [-h] [-p pkgsrc_directory] [-T list_file]
Where:
-a Check all, disregard to -T option. If "# used by" is
included or not.
-h Show this help
-p directory
pkgsrc directory to process (default $PKGSRCDIR)
-T the filename containing list of files (default commonbump)
See Also:
revbump(1) for how to use it.
