# Attempt to move any conda entries in PATH to the front of it.
# IDEs have their own ideas about how PATH should be managed and
# they do dumb stuff like add /usr/bin to the front of it
# meaning conda takes a submissive role and the wrong stuff
# runs (when other conda prefixes get activated they replace
# the wrongly placed entries with newer wrongly placed entries).
#
# Note, there's still condabin to worry about here, and also should
# we not remove all traces of conda instead of just this fixup?
# Ideally we'd have two modes, 'removed' and 'fixed'. I have seen
# condabin come from an entirely different installation than
# CONDA_PREFIX too in some instances and that really needs fixing.
