# It has been written for and tested with MIPSpro 7.3 on IRIX 6.5 
# with a variety of setups.
#
# TODO list (in no particular order):
#
# - Add support for the dllversion free-feature using MIPSpro's
#   soname support.
# - Factor out repetitive code.
# - Decide if `$(<[1])' is better than `$(<)'.
# - Make further use of the `architecture' free feature by using
#   `-TARG' and others.
# - A free feature `mipspro-woff' so users can specify woff
#   values at the command-line.
# - Figure out what to do with the so_locations file.
# - Figure out what to do with the ii_files directory.

# compute directories for invoking MIPSpro: first try ROOT and
# TOOLROOT, which are traditionally used for this purpose.

# For most users, either ROOT/TOOLROOT or
# MIPSPRO_ROOT_DIRECTORY/MIPSPRO_TOOLROOT_DIRECTORY should be
# sufficient. Users needing to further customize the executable

# MIPSPRO_INCLUDE_DIRECTORY, and MIPSPRO_C++INCLUDE_DIRECTORY.
