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'.

i.e. split it on '/' and put it back together again using the current
directory separator. Needed because filenames in the setup script are
always supplied in Unix style, and have to be converted to the local
convention before we can actually use them in the filesystem. Raises
ValueError on non-Unix-ish systems if 'pathname' either starts or
ends with a slash.

u Split a string up according to Unix shell-like rules for quotes and
backslashes. In short: words are delimited by spaces, as long as those
spaces are not escaped by a backslash, or inside a quoted string.
Single and double quotes are equivalent, and the quote characters can
be backslash-escaped. The backslash is stripped from any two-character
escape sequence, leaving only the escaped character. The quote
characters are stripped from any quoted string. Returns a list of
words.

writing to the filesystem). Such actions are special because they
are disabled by the 'dry_run' flag. This method takes care of all

"external action" being performed), and an optional message to

or .pyo files in a __pycache__ subdirectory. 'py_files' is a list
of files to compile; any files that don't end in ".py" are silently
skipped. 'optimize' must be one of the following:
0 - don't optimize (generate .pyc)
1 - normal optimization (like "python -O")
2 - extra optimization (like "python -OO")
If 'force' is true, all files are recompiled regardless of
timestamps.
The source filename encoded in each bytecode file defaults to the
filenames listed in 'py_files'; you can modify these with 'prefix' and
'basedir'. 'prefix' is a string that will be stripped off of each
source filename, and 'base_dir' is a directory name that will be
prepended (after 'prefix' is stripped). You can supply either or both
(or neither) of 'prefix' and 'base_dir', as you wish.
If 'dry_run' is true, doesn't actually do anything that would
affect the filesystem.
Byte-compilation is either done directly in this interpreter process
with the standard py_compile module, or indirectly by writing a
temporary script and executing it. Normally, you should let
'byte_compile()' figure out to use direct compilation or not (see
the source for details). The 'direct' flag is used by the script
generated in indirect mode; unless you know what you're doing, leave
it set to None.
