pypy / pypy / doc / config / objspace.soabi.txt

This option controls the tag included into extension module file names.  The
default is something like `pypy-14`, which means that `import foo` will look for
a file named `` (or `foo.pypy-14.pyd` on Windows).

This is an implementation of PEP3149_, with two differences:

 * the filename without tag `` is not considered.
 * the feature is also available on Windows.

When set to the empty string (with `--soabi=`), the interpreter will only look
for a file named ``, and will crash if this file was compiled for another
Python interpreter.
