# $Id$
#   Fuzz is a script whose purpose is to check through ACE/TAO files for
#   easy to spot (by a perl script, at least) problems.

use File::Find;
use File::Basename;

###### TODO
#
# Add tests for these:
#
# - no relative path to tao_idl in the .dsp files
# - Linking to wrong type of library in dsp's
# - not setting up the release configs correctly in dsp files
# - Guards in .h files
# - no global functions
# - other commit_check checks, tabs, trailing spaces.
# - _narrow() should always have ACE_ENV_ARG_PARAMETER
# - Using ACE_TRY_NEW_ENV (Nanbor suggests using ACE_DECLARE_NEW_CORBA_ENV)
#
# And others in ACE_Guidelines and Design Rules
#
# Also add a -g flag to ignore tao_idl generated files
