gh-71966: Move the module docstring from _pydecimal to decimal (GH-117919) 
Now it is set even if the C implementation is used.

Also add a one-line synopsis.

Stefan Krah b578f8a1ef Issue #19232: Speed up decimal import. Additionally, since _decimal is 
self-contained, this change facilitates maintenance and the Python version
can be easily imported for experimentation.

Stefan Krah 45059eb1d0 1) Prepare libmpdec for the 2.4.0 release. None of the following changes affects 
_decimal:

      o Make all "mpd_t to C integer" conversion functions available in both the
        64-bit and the 32-bit versions.

      o Make all mixed mpd_t/C integer arithmetic functions available in the
        32-bit version.

      o Better handling of __STDC_LIMIT_MACROS for C++ users.

      o Add struct tags (at the request of C++ users).

2) Check for libmpdec.so.2 if --with-system-libmpdec is used.

Raymond Hettinger 6d7e26e959 Get command-line doctest of Lib/decimal.py to work again. 
If tested as '__main__' instead 'decimal', the tracebacks would
abbreviate 'decimal.Inexact' as 'Inexact', breaking the doctests.
