makefile

#
#  makefile
# -------------------------------------------------- part of the fastmat package
#
#  makefile for assisted fastmat package installation.
#
#  NOTE: when working with this file, please keep in mind that line breaks in
#        makefiles expand to one whitespace character! Deal with it. It's POSIX
#
#  Usecases:
#    - install fastmat package system-wide on your machine (needs su privileges)
#        EXAMPLE:        'make install'
#
#    - install fastmat package for your local user only (no privileges needed)
#        EXAMPLE:        'make install MODE=--user'
#
#    - compile all cython source files locally
#        EXAMPLE:        'make compile'
#
#    - uninstall fastmat package
#        EXAMPLE:        'make uninstall'
#        NOTE: If you have installed fastmat manually you need to specify the
#              MODE you have installed fastmat with. e.g. if you installed the
#              package for your local user, you will need to specify this for
#              uninstall as well: 'make uninstall MODE=--user'
#
#    - compile documentation with benchmarks on your machine
#        EXAMPLE:        'make doc [OPTIONS=...]'
#        NOTE: This command will redirect to the target doc of doc/makefile. You
#              may specify additional arguments to the benchmark process with
#              OPTIONS. Your selected PYTHON= version will be passed on.
