def get_platform():
|

"""Return a string that identifies the current platform.
|
||||
|
||||
This is used mainly to distinguish platform-specific build directories and
|
||||
platform-specific built distributions. Typically includes the OS name
|
||||
and version and the architecture (as supplied by 'os.uname()'),
|
||||
although the exact information included depends on the OS; eg. for IRIX
|
||||
the architecture isn't particularly important (IRIX only runs on SGI
|
||||
hardware), but for Linux the kernel version isn't particularly
|
||||
important.
|
||||
|
||||
Examples of returned values:
|
||||
linux-i586
|
||||
linux-alpha (?)
|
||||
solaris-2.6-sun4u
|
||||
irix-5.3
|

irix64-6.2

Windows will return one of:
|
||||
win-amd64 (64bit Windows on AMD64 (aka x86_64, Intel64, EM64T, etc)
|
||||
win-ia64 (64bit Windows on Itanium)
|
||||
win32 (all others - specifically, sys.platform is returned)
|
||||
|
||||
For other non-POSIX platforms, currently just returns 'sys.platform'.
