#!/usr/bin/perl
# RPM (and it's source code) is covered under two separate licenses.
# The entire code base may be distributed under the terms of the GNU
# General Public License (GPL), which appears immediately below.
# Alternatively, all of the source code in the lib subdirectory of the
# RPM source code distribution as well as any code derived from that
# code may instead be distributed under the GNU Library General Public
# License (LGPL), at the choice of the distributor. The complete text
# of the LGPL appears at the bottom of this file.
# This alternative is allowed to enable applications to be linked
# against the RPM library (commonly called librpm) without forcing
# such applications to be distributed under the GPL.
# Any questions regarding the licensing of RPM should be addressed to
# Erik Troan <ewt@redhat.com>.
# a simple script to print the proper name for perl libraries.
# To save development time I do not parse the perl grammmar but
# instead just lex it looking for what I want. I take special care to
# ignore comments and pod's.
# it would be much better if perl could tell us the proper name of a
# given script.
# The filenames to scan are either passed on the command line or if
# that is empty they are passed via stdin.
# If there are lines in the file which match the pattern
# (m/^\s*\$VERSION\s*=\s+/)
# then these are taken to be the version numbers of the modules.
# Special care is taken with a few known idioms for specifying version
# numbers of files under rcs/cvs control.
# If there are strings in the file which match the pattern
# m/^\s*\$RPM_Provides\s*=\s*["'](.*)['"]/i
# then these are treated as additional names which are provided by the
# file and are printed as well.
# I plan to rewrite this in C so that perl is not required by RPM at
# build time.
