# Expands the specialised KDE tags in Makefile.in to (hopefully) valid
# make syntax.
# When called without file parameters, we work recursively on all Makefile.in
# in and below the current subdirectory. When called with file parameters,
# only those Makefile.in are changed.
# The currently supported tags are
#
# {program}_METASOURCES
# where you have a choice of two styles
#   {program}_METASOURCES = name1.moc name2.moc ... [\]
#   {program}_METASOURCES = AUTO
#       The second style requires other tags as well.
#
# To install icons :
#    KDE_ICON = iconname iconname2 ...
#    KDE_ICON = AUTO
#
# For documentation :
#    http://developer.kde.org/documentation/other/developer-faq.html
#
# and more new tags TBD!
#
# The concept (and base code) for this program came from automoc,
# supplied by the following
#
# Matthias Ettrich <ettrich@kde.org>      (The originator)
# Kalle Dalheimer <kalle@kde.org>      (The original implementator)
# Harri Porten  <porten@tu-harburg.de>
# Alex Zepeda  <jazepeda@pacbell.net>
