150 The \fBrpm-config\fR program is a little helper utility for easy |
|
151 configuring and building applications based on the OpenPKG \s-1RPM\s0 library. |
|
152 It can be used to query the C compiler and linker flags which are |
|
153 required to correctly compile and link the application against the |
|
154 \&\s-1RPM\s0 library. |
