The configuration file gets executed during build time. The build system is pretty smart - for a lot of standard compiles it is not necessary to write such a build script. Additionally standard and cross-compilation switches get passed on to configure, make, gcc and friends automatically. Only if modifications to this automatically detected values are needed, a .conf file needs to be created.

Since the possibilities in .conf files have no limits please refer to the the section called “Environment Variables” and later sections.
