#
# This file describes a "configure" script that is used to build
# makefiles for a particular platform.  Process this file using 
# Autoconf version 1.13 in order to generate that script.  All 
# lines of this file up to the AC_INIT macro are ignored.
#
# The build process allows for using a cross-compiler.  But the default
# action is to target the same platform that we are running on.  The
# configure script needs to discover the following properties of the 
# build and target systems:
#
#    srcdir
#
#        The is the name of the directory that contains the
#        "configure" shell script.  All source files are
#        located relative to this directory.
#
#    bindir
#
#        The name of the directory where executables should be
#        written by the "install" target of the makefile.
#
#    program_prefix
#
#        Add this prefix to the names of all executables that run
#        on the target machine.  Default: ""
#
#    ENABLE_SHARED
#
#        True if shared libraries should be generated.
#
#    BUILD_CC
#
#        The name of a command that is used to convert C
#        source files into executables that run on the build
#        platform.
#
#    BUILD_CFLAGS
#
#        Switches that the build compiler needs in order to construct
#        command-line programs.
#
#    BUILD_LIBS
#
#        Libraries that the build compiler needs in order to construct
#        command-line programs.
#
#    BUILD_EXEEXT
#
#        The filename extension for executables on the build
#        platform.  "" for Unix and ".exe" for Windows.
#
#    TARGET_CC
#
#        The name of a command that runs on the build platform
#        and converts C source files into *.o files for the
#        target platform.  In other words, the cross-compiler.
#
#    TARGET_CFLAGS
#
#        Switches that the target compiler needs to turn C source files
#        into *.o files.  Do not include TARGET_TCL_INC in this list.
#        Makefiles might add additional switches such as "-I.".
#
#    TARGET_TCL_LIBS
#
#        This is the library directives passed to the target linker
#        that cause the executable to link against Tcl.  This might
#        be a switch like "-ltcl8.0" or pathnames of library file
#        like "../../src/libtcl8.0.a".
#
#    TARGET_TCL_INC
#
#        This variables define the directory that contain header
#        files for Tcl.  If the compiler is able to find <tcl.h>
#        on its own, then this can be blank.
#
#    TARGET_READLINE_LIBS
#
#        This is the library directives passed to the target linker
#        that cause the executable to link against the readline library.
#        This might be a switch like "-lreadline" or pathnames of library
#        file like "../../src/libreadline.a".
#
#    TARGET_READLINE_INC
#
#        This variables define the directory that contain header
#        files for the readline library.  If the compiler is able 
#        to find <readline.h> on its own, then this can be blank.
#
#    TARGET_LINK
#
#        The name of the linker that combines *.o files generated
#        by TARGET_CC into executables for the target platform.
#
#    TARGET_LIBS
#
#        Additional libraries or other switch that the target linker needs
#        to build an executable on the target.  Do not include
#        on this list any libraries in TARGET_TCL_LIBS and
#        TARGET_READLINE_LIBS, etc.
#
#    TARGET_EXEEXT
#
#        The filename extension for executables on the
#        target platform.  "" for Unix and ".exe" for windows.
#
# The generated configure script will make an attempt to guess
# at all of the above parameters.  You can override any of
# the guesses by setting the environment variable named
# "config_AAAA" where "AAAA" is the name of the parameter
# described above.  (Exception: srcdir cannot be set this way.)
# If you have a file that sets one or more of these environment
# variables, you can invoke configure as follows:
#
#           configure --with-hints=FILE
#
# where FILE is the name of the file that sets the environment
# variables.  FILE should be an absolute pathname.
#
# If you have a Tcl/Tk/BLT source distribution available, then the
# files in that distribution will be used instead of any other
# Tcl/Tk/BLT files the script might discover if you tell the configure
# script about the source tree.  Use commandline options:
#
#         --with-tcl=PATH  --with-tk=PATH  --with-blt=PATH
#
# Or set environment variables config_WITH_TCL, config_WITH_TK, or
# config_WITH_BLT.
#
# This configure.in file is easy to reuse on other projects.  Just
# change the argument to AC_INIT().  And disable any features that
# you don't need (for example BLT) by erasing or commenting out
# the corresponding code.
#
