# Instructions for configuring an fptools package.
#
# There are two ways you can get started with an fptools package, either
# by using the unpacked distribution tree in-situ or by installing the
# package.
#
# Using the package directly is easy, just do `make config', i.e.,
# the distribution will *not* work out-of-the-box, you'll have to do
# this first.
#
# To install the package, you'll have to set one or more of the
# following variables:
#
#  * bindir 
#     path to directory of where you want the executables
#     to be installed.
#  * libdir
#     where you want the library archives to go.
#     Note, if you specify /usr/foo/lib for libdir,
#     the library files for your fptools package will be
#     installed in  /usr/foo/lib/<package>-<version>, i.e.,
#     /usr/foo/lib/ghc-2.02. If you don't want the package/version
#     directory appended, you'll have to modify $(real_libdir)
#     below.
#
#  * datadir
#     path to where the platform-independent files will go.
#     As for libdir, the effective path for the platform-indep
#     stuff is $(datadir)/<package>-<version>. If you want
#     complete control, see $(real_libdir)
#
#  * platform 
#     the platform you're installing for. The configure
#     makes an educated guess what it, so you will only
#     have to set this if it clashes with your reality.
#
#  * infodir
#     where to install the Emacs info files
#  * htmldir
#     where to install the documentation HTML files.
#  * dvidir
#     where to install the DVI files.
#
# Installing the documentation is not via the `install' rule, but
# via the rules: `install-docs', `install-html', `install-dvi'
# and `install-info'.
#
# For more complete instructions, consult the INSTALL file
# that came with the bundle, and/or consult the installation
# documentation in one of the document directories.
