# non-linux-provides is part of RPM, the Red Hat Package Manager.
# non-linux-provides searches a list of directories (based on what OS it's
# being executed on) for shared libraries and interpreters that have been
# installed by some packaging system other than RPM. It then generates a
# spec file that can be used to build a "virtual package" that provides all
# of these things without actually installing any files. This makes it much
# easier to use RPM on non-Linux systems.
#
# Comments: This script is a quick hack. A better solution is to use the
# vendor's package management commands to actually query what's installed, and
# build one or more spec files based on that. This is something
# I intend to write, probably in perl, but the need for something like this
# first effort was great, so I didn't want to wait until the better solution
# was done.

%description
This is a virtual RPM package. It contains no actual files. It uses the
\`Provides' token from RPM 3.x and later to list many of the shared libraries
and interpreters that are part of the base operating system and associated
subsets for $osname.
This virtual package was constructed based on the vendor/system software
installed on the $osname machine named $hostname, as of the date
$date.
