dnl  Why do we need python?

dnl  Python scripts are used to auto-generate about 3000 lines of C
dnl  and XML code that wraps (part of) the existing Gaim API so that
dnl  it is now accessible through DBUS.

dnl  Python is only required if --enable-dbus is used, and only for
dnl  the build process to generate the code, not for running gaim.
dnl  This autogenerated code is system-independent, so in principle we
dnl  can generate all of it before shipping.  But I thought adding
dnl  auto-generated stuff to the repository is inelegant.
dnl  Alternatively, these python scripts could be rewritten
dnl  in C (brrrr ...).
