# Changes Makefile.in to work correctly with moc files. When called
# without parameters, automoc works recursively on all Makefile.in in
# and below the current subdirectory. When called with parameters,
# only these Makefile.in are changed.
# The Makefile.in should have an entry with the following syntax:
#
# {program}_METASOURCES = USE_AUTOMOC [{suffix}]
#
# Moc files will have a 'cpp' suffix unless overriden by the optional
# {suffix} parameter.
# Be careful not to use a suffix that isn't used by at least one
# of the main source files in {program}_SOURCES.
#
# 1998-07-23 Harri Porten <porten@tu-harburg.de>
# * small bugfixes for MOCSOURCES
# 1998-11-08 Alex Zepeda <garbanzo@hooked.net>
# * tweak it so it will run from a "common" directory.
# 1998-11-11 Harri Porten <porten@tu-harburg.de> & David Faure <faure@kde.org>
# * bug fix for invocation with arguments
# 1998-11-16 Harri Porten <porten@kde.org>
# * take care of "ar" object files, too.
# (as proposed by Martin Vogt <mvogt@rhrk.uni-kl.de>)
# 1999-01-13 Harri Porten <porten@kde.org>
# * implemented {suffix} parameter
# 1999-01-16 Stephan Kulow <coolo@kde.org>
# * implemented support for included MOC files and command line
# parameters
