# prebuild.sh script (maintainers only) 
# Written by Nicolas Calimet and Christoph Hormann
#
# This prebuild.sh script prepares the source tree for building the
# Unix/Linux version of POV-Ray.  Unlike the former versions, the
# prebuild procedure does not change the directory structure, so that
# the overall layout of the UNIX source distribution remains consistent
# with the other supported architectures (namely Windows and Macintosh).
# Yet, some "standard" files such as configure, README, INSTALL, etc.
# are placed in the root directory to give the expected GNUish look to
# the distribution.
#
# The purpose of this script is to create the 'configure' and various
# 'Makefile.am' shell scripts, as well as modify/update some generic files
# (e.g. doc).
#
# Running prebuild.sh requires:
#   1) GNU autoconf >= 2.68 and GNU automake >= 1.9
#   2) perl and m4 (should be on any system, at least Linux is okay)
#   3) Run from the unix/ directory where the script is located.
#
# Prepare all but the doc/ directory using:
#   % ./prebuild.sh
#
# Clean up all files and folders created by this script (but docs):
#   % ./prebuild.sh clean
#
# The unix-specific documentation is created seperately since it requires
# lots of processing time as well as a bunch of other programs such as PHP.
# See ../documentation/povdocgen.doc for details.
# The "all" option builds all docs, otherwise only html docs are created.
# Any other option (e.g. "skip ta") replaces the default.
#   % ./prebuild.sh doc(s) [option]
#
# Clean up the docs:
#   % ./prebuild.sh doc(s)clean
#
# Note that the 'clean' and 'doc(s)(clean)' options are mutually exclusive.
