Manages .packlist files. Supports an extended .packlist format. The original format is a list of absolute pathnames, one pathname per line. In the extended format, each line can also contain a list of attributes as key/value pairs, which are used by the installperl script. For example:

/usr/local/bin/perl from=/usr/local/pbeta/bin/perl5.005 type=link
/usr/local/bin/perl5.005 type=file
/usr/local/lib/perl5/5.005/AnyDBM_File.pm type=file
