#
# DESCRIPTION:
#   I like to install my software by using configure with --prefix set to the
#   top-level directory of the particular package I am installing.  I then make
#   softlinks in /usr/local/bin, /usr/local/man/man1, etc. to the actual
#   locations of the files.
#
#   This strategy doesn't work with some software, though, like GNU's gcc,
#   because it really needs to know what your main /usr/local directory is.  In
#   this case, you can use this script as install.sh's $MVPROG to trick it into
#   thinking it's moving the files into /usr/local, whereas it's actually moving
#   them into a directory off of $SOFTLINK_MVPROG_DIR and then creating
#   softlinks in /usr/local.
#
# EXAMPLE:
#   % cd /usr/local/binutils-2.8.1
#   % setenv SOFTLINK_MVPROG_DIR /usr/local/binutils-2.8.1/install
#   % setenv MVPROG softlink_mvprog
#   % make install
