Helping us

[Akim Demaille]

Here are a few things people could do to help the team:

- Starting an FAQ in Texinfo (we need to put on the web etc.)
  For a start it should include answer about `possible undefined dnl',
  the problem with m4_diversion_number, the problem with autoheader
  complaining about trace.sh etc.

  Proposing an empty shell is just fine, as it would help us.

- Propagating AC_INCLUDES_DEFAULT in acfunctions.m4.  Just have a look
  at other macros there using it.

- Fill the functions zoo in the documentation (an empty @table for the
  time being).


Thanks!
