-# This module is maintained by Marc-Andre Lemburg <ma...@eg...>.
-# If you find problems, please submit bug reports/patches via the
-# Python SourceForge Project Page and assign them to "lemburg".
-#
-# Note: Please keep this module compatible to Python 1.5.2.
-#
-# Still needed:
-# * more support for WinCE
-# * support for MS-DOS (PythonDX ?)
-# * support for Amiga and other still unsupported platforms running Python
-# * support for additional Linux distributions
-#
-# Many thanks to all those who helped adding platform-specific
-# checks (in no particular order):

-# Charles G Waldman, David Arnold, Gordon McMillan, Ben Darnell,
-# Jeff Bauer, Cliff Crawford, Ivan Van Laningham, Josef

-# Colin Kong, Trent Mick, Guido van Rossum
-#
-# History:
-#
-# <see CVS and SVN checkin messages for history>
-#
-# 1.0.3 - added normalization of Windows system name
-# 1.0.2 - added more Windows support
-# 1.0.1 - reformatted to make doc.py happy
-# 1.0.0 - reformatted a bit and checked into Python CVS
-# 0.8.0 - added sys.version parser and various new access
-# APIs (python_version(), python_compiler(), etc.)
-# 0.7.2 - fixed architecture() to use sizeof(pointer) where available
-# 0.7.1 - added support for Caldera OpenLinux
-# 0.7.0 - some fixes for WinCE; untabified the source file
-# 0.6.2 - support for OpenVMS - requires version 1.5.2-V006 or higher and
-# vms_lib.getsyi() configured
-# 0.6.1 - added code to prevent 'uname -p' on platforms which are
-# known not to support it
-# 0.6.0 - fixed win32_ver() to hopefully work on Win95,98,NT and Win2k;
-# did some cleanup of the interfaces - some APIs have changed
-# 0.5.5 - fixed another type in the MacOS code... should have
-# used more coffee today ;-)
-# 0.5.4 - fixed a few typos in the MacOS code
-# 0.5.3 - added experimental MacOS support; added better popen()
-# workarounds in _syscmd_ver() -- still not 100% elegant
-# though
-# 0.5.2 - fixed uname() to return '' instead of 'unknown' in all
-# return values (the system uname command tends to return
-# 'unknown' instead of just leaving the field emtpy)
-# 0.5.1 - included code for slackware dist; added exception handlers
-# to cover up situations where platforms don't have os.popen
-# (e.g. Mac) or fail on socket.gethostname(); fixed libc
-# detection RE
-# 0.5.0 - changed the API names referring to system commands to *syscmd*;
-# added java_ver(); made syscmd_ver() a private
-# API (was system_ver() in previous versions) -- use uname()
-# instead; extended the win32_ver() to also return processor
-# type information
-# 0.4.0 - added win32_ver() and modified the platform() output for WinXX
-# 0.3.4 - fixed a bug in _follow_symlinks()
-# 0.3.3 - fixed popen() and "file" command invokation bugs
-# 0.3.2 - added architecture() API and support for it in platform()
-# 0.3.1 - fixed syscmd_ver() RE to support Windows NT
-# 0.3.0 - added system alias support
-# 0.2.3 - removed 'wince' again... oh well.
-# 0.2.2 - added 'wince' to syscmd_ver() supported platforms
-# 0.2.1 - added cache logic and changed the platform string format
-# 0.2.0 - changed the API to use functions instead of module globals
-# since some action take too long to be run on module import
-# 0.1.0 - first release
