michael@13: B<rpm-config> - OpenPKG RPM library build utility
michael@13: 
michael@13: =head1 VERSION
michael@13: 
michael@13: OpenPKG RPM RPM_VERSION
michael@13: 
michael@13: =head1 SYNOPSIS
michael@13: 
michael@13: B<rpm-config>
michael@13: [B<--help>]
michael@13: [B<--version>]
michael@13: [B<--cc>]
michael@13: [B<--cppflags>]

michael@13: [B<--ldflags>]
michael@13: [B<--libs>]
michael@13: 
michael@13: =head1 DESCRIPTION
michael@13: 
michael@13: The B<rpm-config> program is a little helper utility for easy
michael@13: configuring and building applications based on the OpenPKG RPM library.
michael@13: It can be used to query the C compiler and linker flags which are
michael@13: required to correctly compile and link the application against the
michael@13: RPM library.
michael@13: 
michael@13: =head1 OPTIONS
michael@13: 
michael@13: B<rpm-config> accepts the following options:
michael@13: 
michael@13: =over 4
michael@13: 
michael@13: =item B<--help>
michael@13: 
michael@13: Prints the short usage information.
michael@13: 
michael@13: =item B<--version>
michael@13: 
michael@13: Prints the version number and date of the installed RPM library.
michael@13: 
michael@13: =item B<--cc>
michael@13: 
michael@13: =item B<--cppflags>
michael@13: 
michael@13: Prints the C pre-processor flags (C<-I>) which are needed to compile the
michael@13: RPM-based application. The output is usually added to the C<CPPFLAGS>
michael@13: variable of the applications C<Makefile>.
michael@13: 
michael@13: =item B<--cflags>
michael@13: 
michael@13: Prints the C compiler flags which are needed to compile the RPM-based
michael@13: application. The output is usually added to the C<CFLAGS> variable of the
michael@13: applications C<Makefile>.
michael@13: 
michael@13: =item B<--ldflags>
michael@13: 
michael@13: Prints the linker flags (C<-L>) which are needed to link the application with
michael@13: the RPM library. The output is usually added to the C<LDFLAGS> variable of
michael@13: the applications C<Makefile>.
michael@13: 
michael@13: =item B<--libs>
michael@13: 
michael@13: Prints the library flags (C<-l>) which are needed to link the application with
michael@13: the RPM library. The output is usually added to the C<LIBS> variable of the
michael@13: applications C<Makefile>.
