BUILDPKG - package build tools -> examples/enhanced

This way you can do more than one CONFIGURE, BUILD and INSTALL steps before generating the package(s).

Here is an example using this feature cdrtools-2.0-i386-1.def.
This way you can create multiple packages out of one compilation.

Here are some examples files demonstrating this feature...
cups-1.1.18-i386-1.def, libcups-1.1.18-i386-1.filelist, libcups_dev-1.1.18-i386-1.filelist, libcups_doc-1.1.18-i386-1.filelist
