#

# 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.

#
