#           Notes on installing local software


# This was quickly hacked up by James Leifer and is probably full of
# bugs.  No warrenties, no support.  Please don't use these recipes
# instead of thinking for yourself or else *anything* could happen.


#---------------------------------------------------------------
#                         STRATEGY
#

# we install into, for example, /opt/ocaml/3.07pl2/ and we then
# symlink from /usr/local . this way we can easily uninstall by
# searching for symlinks


#---------------------------------------------------------------
#                             GENERAL ASSUMPTIONS
#

umask 022
export OLDMYPREFIX=#/opt/ocaml/3.06 for example;  **think**: put in the old prefix (if any)
export MYPREFIX=#/opt/ocaml/3.07pl2 for example;  **think**: put in the new prefix

sudo mkdir -p "$MYPREFIX"
sudo chown leifer:moscova "$MYPREFIX"

#--------------------------------------------------------------------
#                       GENERAL UNINSTALL PROCEDURE
#

#as **root**, view the links to it:
( if test "z$OLDMYPREFIX" = "z"; then echo stopping: please set OLDMYPREFIX first; exit 1; fi ) && \
find /usr/local -type l -lname "$OLDMYPREFIX"/\* -exec echo "{}" \;

#if ok, rerun replacing echo by rm


#---------------------------------------------------------------------
#                  GENERAL INSTALL PROCEDURE 
#

# as **root**
( if test "z$MYPREFIX" = "z"; then echo stopping: please set MYPREFIX first; exit 1; fi ) && \
