+# History:\r
+#\r
+# <see CVS and SVN checkin messages for history>\r
+#\r
+# 1.0.7 - added DEV_NULL\r
+# 1.0.6 - added linux_distribution()\r
+# 1.0.5 - fixed Java support to allow running the module on Jython\r
+# 1.0.4 - added IronPython support\r
+# 1.0.3 - added normalization of Windows system name\r
+# 1.0.2 - added more Windows support\r
+# 1.0.1 - reformatted to make doc.py happy\r
+# 1.0.0 - reformatted a bit and checked into Python CVS\r
+# 0.8.0 - added sys.version parser and various new access\r
+# APIs (python_version(), python_compiler(), etc.)\r
+# 0.7.2 - fixed architecture() to use sizeof(pointer) where available\r
+# 0.7.1 - added support for Caldera OpenLinux\r
+# 0.7.0 - some fixes for WinCE; untabified the source file\r
+# 0.6.2 - support for OpenVMS - requires version 1.5.2-V006 or higher and\r
+# vms_lib.getsyi() configured\r
+# 0.6.1 - added code to prevent 'uname -p' on platforms which are\r
+# known not to support it\r
+# 0.6.0 - fixed win32_ver() to hopefully work on Win95,98,NT and Win2k;\r
+# did some cleanup of the interfaces - some APIs have changed\r
+# 0.5.5 - fixed another type in the MacOS code... should have\r
+# used more coffee today ;-)\r
+# 0.5.4 - fixed a few typos in the MacOS code\r
+# 0.5.3 - added experimental MacOS support; added better popen()\r
+# workarounds in _syscmd_ver() -- still not 100% elegant\r
+# though\r
+# 0.5.2 - fixed uname() to return '' instead of 'unknown' in all\r
+# return values (the system uname command tends to return\r
+# 'unknown' instead of just leaving the field emtpy)\r
+# 0.5.1 - included code for slackware dist; added exception handlers\r
+# to cover up situations where platforms don't have os.popen\r
+# (e.g. Mac) or fail on socket.gethostname(); fixed libc\r
+# detection RE\r
+# 0.5.0 - changed the API names referring to system commands to *syscmd*;\r
+# added java_ver(); made syscmd_ver() a private\r
+# API (was system_ver() in previous versions) -- use uname()\r
+# instead; extended the win32_ver() to also return processor\r
+# type information\r
+# 0.4.0 - added win32_ver() and modified the platform() output for WinXX\r
+# 0.3.4 - fixed a bug in _follow_symlinks()\r
+# 0.3.3 - fixed popen() and "file" command invokation bugs\r
+# 0.3.2 - added architecture() API and support for it in platform()\r
+# 0.3.1 - fixed syscmd_ver() RE to support Windows NT\r
+# 0.3.0 - added system alias support\r
+# 0.2.3 - removed 'wince' again... oh well.\r
+# 0.2.2 - added 'wince' to syscmd_ver() supported platforms\r
+# 0.2.1 - added cache logic and changed the platform string format\r
+# 0.2.0 - changed the API to use functions instead of module globals\r
+# since some action take too long to be run on module import\r
+# 0.1.0 - first release\r
