When debugging or testing improvements to the python build system (python.mk)
in Maneage, it would be good to have a clean method for uninstalling _all_
python libraries and binaries and python module libraries and binaries.

My best recent attempt was

rm -fv .local/version-info/python/; rm -fv .local/bin/python; rm -fr
.local/lib/python*; rm -fr .build/.cache/Python-Eggs/; rm -fv
.local/version-info/proglib/python-3.10.6; rm -fv .local/bin/cy*; rm -fv
.local/version-info/proglib/cy*; rm -fvr .local/include/python3.10* ; rm -fv
.local/bin/f2py*

but on doing './project configure --existing-conf' I still got fatal errors of
the style

FileExistsError: File already exists: ...


The only practical method I found of uninstalling python, in order to get a
clean test of an update to python, was to remove the whole '.build/' tree. 
(In principle, removing '.build/software/' should be enough.)

(In Debian, _aptitude purge PACKAGE_ removes all traces of the package,
including any configure files installed with PACKAGE and subsequently modified
by the sysadmin. An alternative is _aptitude remove PACKAGE_ , which does not
remove configuration files.)
