This provides an easy way to install new or old Python versions on Unixish systems. It is mainly intended for testing Mercurial with different Python versions. Example: $ cd build $ make -f ../contrib/Makefile.python python PYTHONVER=2.4 PREFIX=/tmp/p24 $ /tmp/p24/bin/python -V Python 2.4 Tested on Fedora, Debian and Ubuntu with Python versions from 2.4 to 2.7.6. Most Python versions need some workarounds to compile on Debian-ish systems. The workarounds do not do any significant harm on Fedora.
