This is a port of GNU less 444  to MSDOS/DJGPP.

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

        The port no longer uses the included DJGPP tailored files called
        defines.ds and Makefile.dsg.  The sources will be configured using
        the supplied configure script. All the required DJGPP specific files
        are store in the /djgpp directory.
        The less port will look for the system wide lesskey file called sysless
        in the canonical directory /dev/envDJDIR/etc.  If it cannot be found
        there, the old DOS one will be load instead, this is c:\_sysless.
        The local lesskey file is called .less and will be loaded from the
        $HOME directory.  If the file does not exists or there is no LFN
        support then the port will try to load _less either from the $HOME
        directory or if this fails from the dos path.  For the history file
        the unix filename .lesshst is used before the dos filename _lesshst
        is tried.  The same applies to the .less file.
        This means that unix paths and filenames always takes precedence over
        the dos ones.  Only if they do not exist or if LFN support is not
        available then the dos paths and filenames will be used.
        At run time, it will be detected if edit is used as editor.  In this
        case the command line options passed to the editor will contain only
        the name of the file to be loaded and any other information will be
        descarded.
        If you prefer to configure for some other default editor, you will have
        to reconfigure and recompile the port passing the "editor name" command
        line option to config.bat.  "name" is the name of the editor.
        This port also offers perl-regexp (pcre) support so if you want to
        compile the sources with this feature you will have to install the pcre
        library first.  This is available as:
          ftp://ftp.delorie.com/pub/djgpp/current/v2tk/pcre812b.zip
        or
          ftp://ftp.delorie.com/pub/djgpp/beta/v2tk/pcre812b.zip
        If you want this feature you will have to reconfigure and recompile the
        port passing the "pcre" command line option to config.bat.  By default,
        the port is compiled without pcre support and with edit as default
        editor.
        To be able to compile the sources snprintf() and some other functions
        are required.  These functions are provided by libsupp.a, so you will
        need to install the package:
          ftp://ftp.delorie.com/pub/djgpp/beta/v2tk/lsupp64a.zip
        before you can configure and compile the sources.

        As usual, all djgpp specific files (config.bat, diffs, README files,
        etc.) are located in the /djgpp directory.  The changes I have done
        to the sources are documented in the /djgpp/diffs file.

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


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

2.1.:   Copy the binary distribution into the top DJGPP installation directory,
        just unzip it preserving the directory structure running one of the
        following commands:
          unzip32 lss444b.zip      or
          djtarx lss444b.zip       or
          pkunzip -d lss444b.zip


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

3.1.:   Create a temporary directory and copy the source package into the
        directory.  If you download the source distribution from one of the
        DJGPP sites, just unzip it preserving the directory structure
        running one of the following commands:
          unzip32 lss444s.zip      or
          djtarx lss444s.zip       or
          pkunzip -d lss444s.zip

3.2.:   To build the binaries you will need the following binary packages:
          djdev203.zip (or a later but NOT a prior version)
          bsh205bbr3.zip (or a later but NOT a prior version)
          gccNNNb.zip, gppNNN.zip, bnuNNNb.zip, makNNNb.zip, filNNNb.zip,
          shlNNNb.zip, txtNNNb.zip, txiNNNb.zip, grepNNNb.zip, sedNNNb.zip,
          pcreNNNb.zip, mktmpNNb.zip and gwkNNNb.zip.

        NNN represents the latest version number of the binary packages.  All
        this packages can be found in the /v2gnu directory of any
        ftp.delorie.com mirror.
        You will need bsh205bbr3.zip or later and *NOT* a prior version or
        the build will fail.  The same applies to djdev203.zip.

3.3.:   If for some reason you want to reconfigure the package cd into the top
        srcdir (less-444) and run the following commands:
          del djgpp\config.cache
          make clean
          djgpp\config

        Please note that you *MUST* delete the config.cache file in the djgpp
        subdir 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\less-444\djgpp\config x:/src/gnu/less-444

        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\less-444\djgpp\config x:/src/gnu/less-444

        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.in's 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.:   To install the binaries, and info docs 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:
          make install prefix=z:/some/other/place
