#
# 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.
#
#    TCL_*
#
#        Lots of values are read in from the tclConfig.sh script,
#        if that script is available.  This values are used for
#        constructing and installing the TCL extension.
#
#    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_EXEEXT
#
#        The filename extension for executables on the
#        target platform.  "" for Unix and ".exe" for windows.
#
# 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.
