+# - The program we need to find is iconv, which comes with glibc. The user

+dnl Python 2.7, 2.6, 2.5, and then 2.4 are tried in turn.
+dnl auto - Same as "yes", but if python is missing from the system,

+dnl /path/to/python/exec-prefix -
+dnl Use the python located in this directory.
+dnl If /path/to/python/exec-prefix/bin/python exists, use it to find
+dnl the compilation parameters. Otherwise use

+dnl NOTE: This case is historical. It is what was done for 7.0/7.1
+dnl but is deprecated.
+dnl /path/to/python/executable -
+dnl Run python-config.py with this version of python to fetch the
+dnl compilation parameters.
+dnl NOTE: This needn't be the real python executable.
+dnl In a cross-compilation scenario (build != host), this could be
