+PyPy is a very compliant implementation of the Python language.  PyPy
+has several advantages and distinctive features: speed (Just-in-Time
+compiler), lower memory usage for large programs, sandboxing and
+stackless mode.
+
+This script is for PyPy implementation of Python 2.7 from sources.
+Beware: this takes up a lot of time and about 5Gb of RAM in a 64bit
+system. And still 3Gb on a 32bit system.
+
+Note: This package does conflict with pypy, overwriting files.
+
+OPTIONAL: pypy or PyPy, available on SBo.
+If pypy2 is installed, from binary repackaging using pypy, or from
+a previous installation of PyPy, it'll be used instead of CPython2.7,
+as it is twice as fast.
+It might even be better for a first build of PyPy to build and install
+pypy first.
+pycparser is required only when using Slackware's CPython2.7
+for building.
+
+REQUIRES: you need one of pycparser, pypy or PyPy.
