ccombine is based on a script in the Zstd source called combine.sh.
I rewrote it in Python because the original is very slow (see
the benchmark). The only change is a better command-line interface.
It can be used to create an amalgamated distribution of your library for easy embedding into another source tree. Some reasons to do this are outlined in nothings/stb and "SQLite is really easy to compile".
You can install it by cloning and running pip install .. This will install a
script called ccombine into your Python environment. Alternatively, you can
simply download ccombine.py. The only requirement is Python 3.7 and
its standard library.
If you need 3.6 compatibility see the python36-compat branch. Note that it is often rebased and force-pushed.
