It helps to keep the files +in sync because it never forgets which files need to be updated, nor what +information should be inserted in each file. + +It takes one parameter that says what the mode of update should be, which +may be one of 'develop', 'release', or 'post'. + +In 'develop' mode, which is what someone would use as part of their own +development practices, the release type is forced to be 'alpha' and the +patch level is the string 'yyyymmdd'. Otherwise, it's the same as the +'release' mode. + +In 'release' mode, the release type is taken from ReleaseConfig and the +patch level is calculated from the release date for non-final runs and +taken from the version tuple for final runs. It then inserts information +in various files: + - The RELEASE header line in src/CHANGES.txt and src/Announce.txt. + - The version string at the top of src/RELEASE.txt. + - The version string in the 'default_version' variable in SConstruct + and QMTest/TestSCons.py. + - The copyright years in SConstruct and QMTest/TestSCons.py. + - The month and year (used for documentation) in SConstruct. + - The unsupported and deprecated Python floors in QMTest/TestSCons.py + and src/engine/SCons/Script/Main.py + - The version string in the filenames in README. + +In 'post' mode, files are prepared for the next release cycle: + - In ReleaseConfig, the version tuple is updated for the next release + by incrementing the release number (either minor or micro, depending + on the branch) and resetting release type to 'alpha'. + - A blank template replaces src/RELEASE.txt. + - A new section to accumulate changes is added to src/CHANGES.txt and + src/Announce.txt. +""" +# +# Copyright (c) 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010 The SCons Foundation +# +# Permission is hereby granted, free of charge, to any person obtaining +# a copy of this software and associated documentation files (the +# "Software"), to deal in the Software without restriction, including +# without limitation the rights to use, copy, modify, merge, publish, +# distribute, sublicense, and/or sell copies of the Software, and to +# permit persons to whom the Software is furnished to do so, subject to +# the following conditions: +# +# The above copyright notice and this permission notice shall be included +# in all copies or substantial portions of the Software. +# +# THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY +# KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE +# WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND +# NONINFRINGEMENT.
