possible. It makes this information available via function APIs.
If called from the command line, it prints the platform
information concatenated as single string to stdout. The output
format is usable as part of a filename.

(which defaults to the Python interpreter) is linked against.
Returns a tuple of strings (lib,version) which default to the
given parameters in case the lookup fails.
Note that the function has intimate knowledge of how different
libc versions add symbols to the executable and thus is probably
only usable for executables compiled using gcc.
The file is read and scanned in chunks of chunksize bytes.

(name, version, branch, revision, buildno, builddate, compiler)
referring to the Python implementation name, version, branch,
revision, build number, build date/time as string and the compiler
identification string.
Note that unlike the Python sys.version, the returned value
for the Python version will always include the patchlevel (it
defaults to '.0').
The function returns empty strings for tuple entries that
cannot be determined.
sys_version may be given to parse an alternative version
string, e.g. if the version was read from a different Python
interpreter.

with as much useful information as possible (but no more :).
The output is intended to be human readable rather than
machine parseable. It may look different on different
platforms and this is intended.
If "aliased" is true, the function will use aliases for
various platforms that report system names which differ from
their common names, e.g. SunOS will be reported as
Solaris. The system_alias() function is used to implement
this.
Setting terse to true causes the function to return only the
absolute minimum information needed to identify the platform.
