#
# 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.
#
# 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.
#
# 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.
