# configure - configure script for AnaGram
# usage: path-to-source/configure [options]
# for options, do configure --help, or read down.
#
# Note: this is a hand-written script, not GNU autoconf output.
# Its primary purpose is to set up the build tree, not to perform
# tests on the build platform.
#
# Also note: changing to autoconf will not make this any easier, or
# add any useful functionality for free, so please don't bother
# suggesting it.
#
# Supported compilers and targets are listed below. Note that there is
# vestigial support in the source tree for various other Windows
# compilers (Borland, Watcom, etc.) - I don't have these, but will
# cheerfully add support if someone tells me how to invoke them and
# sends patches to clean up the template instantiations. I will also
# take patches for supporting for other Unix compilers. And if anyone
# wants to update the once-upon-a-time Amiga support, I'll even take 
# patches for that.
#
# Also, this script should not be expected to work for native builds
# on Windows. I don't have a Windows machine, Windows is a crippled
# platform, and it's too much trouble to sort out. If someone wants to
# make it work under Cygwin, however, I'll take the patches.

Usage: PATH-TO-SOURCE/configure [options] [ostype]
Options:
    --with-compiler=COMPILER    Choose compiler (see below)
    --with-ptests=DIR           Use private testsuite in DIR
    --enable-gui=GUI            Enable a GUI (see below)
    --disable-gui               Build command-line version only
    --enable-maintainer-mode    Set maintainer-specific build options
    --enable-debug              Enable debugging information
    --enable-prof               Enable profiling
For Unix installs:
    --destdir=DIR               Set install chroot (default: none)
    --prefix=DIR                Set install prefix (default: /usr/local)
    --bindir=DIR                Install directory for binaries
    --libdir=DIR                Install directory for libraries
    --mandir=DIR                Install directory for man pages
    --docdir=DIR                Install directory for HTML docs
    --examplesdir=DIR           Install directory for examples
Compilers:
    gcc                         The GNU compiler (gcc/g++).
    vacpp                       IBM Visual Age C++ for Windows
GUIs:
    vaclgui                     The IBM Visual Age C++ for Windows GUI
    dummygui                    Equivalent to --disable-gui
OSes:
    native                      Current Unix type (default)
    windows                     Cross-compiled Windows
    *-* or *-*-*                A cross-compiled Unix type
Notes:
    1. Compiling in the source directory is not supported. Run
       configure in a subdirectory or somewhere else.
    2. Native builds on Windows are not supported.
    3. Read the install instructions before cross-compiling.
