+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 builds PyPy implementation of Python 3.9 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 pypy3, overwriting files.
+
+OPTIONAL: pypy or PyPy, available on SBo.
+If pypy2 is installed, from binary repackaging using pypy, or from
+sources using PyPy, it'll be used instead of CPython2.7, as it is
+twice as fast.
+PyPy, even for Python3.9, only builds using a Python2.7 interpreter.
+pycparser is required only when using Slackware's CPython2.7
+for building.
+
+REQUIRES: you need one of pycparser, pypy or PyPy.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
