This is a port of GNU Readline 6.1 to MSDOS/DJGPP.

1.:     DJGPP specific changes.
        =======================

        - The port is based on the port of readline 2.2 and uses the termios
        emulation provided by it.  It has been slightly adjusted to work with
        DJGPP 2.04.  It also supports copying from Windows clipboard as the
        readline port from bash does if the rquired functions are provided by
        the used DOS version.  Most of the other changes are required to handle
        DOS specific slash and backslash issues and to pacify the compiler.

        - The port will check at run time if LFN support is available or not.
        If available, then it will look for ".inputrc" and ".history"  as
        configuration files.  If one of them is not available then it will try
        _inputrc" and/or "_history" as alternative file names.  This means that
        if LFN support is available, the POSIX file names will always be tried
        before the DOS file names are tried.  Of course, if only SFN support is
        available only the DOS versions of the file names will be tried.

        - The port will try to load the system wide configuration file using
        the file name "/dev/env/DJDIR/etc/inputrc" instead of the hard coded
        "/etc/inputrc".  The system wide INPUTRC file is always tried to be
        load if the loading of "~/.inputrc" fails and before "~/_inputrc" is
        tried to be load on LFN systems.


        As usual, all djgpp specific files (config.bat, diffs, README files,
        etc.) are located in the /djgpp directory.


2.:     Installing the binary package.
        ==============================

2.1.:   Copy the binary distribution into the top DJGPP installation directory
        and unzip it running *ONE* of the following commands:
          unzip32 rdln61b.zip      or
          djtarx rdln61b.zip       or
          pkunzip -d rdln61b.zip

        For further information about GNU Readline please read the info docs and the
        NEWS file.


3.:     Building the binaries from sources.
        ===================================

3.1.:   To build the binaries you will need the following binary packages:
          djdev203.zip (patch level 2, see the djdev203.dsm or a later version)
          bsh205bbr3.zip (or a later but NOT a prior version)
          gccNNNb.zip, bnuNNNb.zip, makNNNb.zip, filNNNb.zip, shlNNNb.zip,
          txtNNNb.zip, txiNNNb.zip, grepNNNb.zip, sedNNNb.zip, difNNNb.zip
          and perlNNNb.zip

        All this packages can be found in the v2gnu directory of ftp.delorie.com
        and any mirror.  NNN stands for the newest port versions available when
        this port was build but older may do the work as well.

3.2.:   Create a temporary directory. Copy the source package: rdln61s.zip
        into the directory and unzip it running ONE of the following commands:
          unzip32 rdln61s.zip      or
          djtarx rdln61s.zip       or
          pkunzip -d rdln61s.zip

3.3.:   If for some reason you want to reconfigure the package cd into the top
        srcdir (readline-6.1) and run the following commands:
          del djgpp\config.cache
          make distclean
          djgpp\config

        Please note that you *MUST* delete the config.cache file in the /djgpp
        directory or you will not really reconfigure the sources because the
        configuration informations will be read from the cache file instead
        of being newly computed.
        To build the programs in a directory other than where the sources are,
        you must add the parameter that specifies the source directory,
        e.g:
          x:\src\gnu\readline-6.1\djgpp\config x:/src/gnu/readline-6.1

        Lets assume you want to build the binaries in a directory placed on a
        different drive (z:\build in this case) from where the sources are,
        then you will run the following commands:
          z:
          md \build
          cd \build
          x:\src\gnu\readline-6.1\djgpp\config x:/src/gnu/readline-6.1

        The order of the options and the srcdir option does not matter. You
        *MUST* use forward slashes to specify the source directory.

        The batch file will set same environment variables, make MSDOS specific
        modifications to the Makefile.ins and supply all other needed options
        to the configure script.

3.4.:   To compile the package run from the top srcdir the command:
          make

3.5.:   The package provides no test suite but you can check if the port works
        by compiling the sample programs in the /examples directory.

3.6.:   To install the binary, info docs and man pages run the following command
        from the top srcdir:
          make install

        This will install the products into your DJGPP installation tree given
        by the default prefix "/dev/env/DJDIR". If you prefer to install them
        into some other directory you will have to set prefix to the appropriate
        value.
        Example:
          make install prefix=z:/some/other/dir
