OK, so how about:

Scripting inside of spec files

Inside of a spec file, sometimes it is necessary to call a programming or
scripting language during %setup, %build, or %install. In Fedora, spec
files may in general only use the following languages for this purpose:

1. Python
2. Perl
3. awk/sed

Also, if your package already BuildRequires a specific scripting language
(such as Ruby, or Tcl) as part of its normal compile process, it may also be
called from the spec file.
