-?X:
-?X: There are two schools of thoughts here. Some people correctly argue that
-?X: the user has a better chance than we do of setting a reasonable PATH and
-?X: others argue that Configure is the best place there is to set up a suitable
-?X: PATH. Well, here we try to compromize by keeping the user's PATH and
-?X: appending some directories which are known to work on some machine or the
-?X: other. The rationale behind this being that a novice user might not have a
-?X: proper environment variable set, and some directories like /etc (where
-?X: chown is located on some BSD systems) may be missing--RAM.
-?X:
-?X: SVR4 adds an /opt directory for optional packages. Some sites use
-?X: various permutations on /opt as opposed to /usr or /usr/local.-- ADO
-?X:
-?X: We only add directories that are not already in the PATH of the
-?X: user and the directories must exist also.
