1.153 +The \fBrpm-config\fR program is a little helper utility for easy
1.154 +configuring and building applications based on the OpenPKG \s-1RPM\s0 library.
1.155 +It can be used to query the C compiler and linker flags which are
1.156 +required to correctly compile and link the application against the
1.157 +\&\s-1RPM\s0 library.
