UNIX installation specific functions.  Please read this file.  

0. Building and installing JED requires that you also have the S-Lang library
   to installed.  See http://www.jedsoft.org/slang/download.html for
   information about obtaining the library.

  * NOTE: Many Unix distributions distribute a version of the library
    that that may be used to compile against.  For example, on Debian
    Linux the library is in the "libslang2-dev" package, which may be
    installed using:

      apt-get install libslang2-dev

  * NOTE: Since the jed editor is a conforming slang application, it
    makes use of the slsh library files, which are part of the slang
    distribution.  If you install slang from source, then these files
    will also get installed.  However, on Debian Linux and its derivatives,
    these files have been placed into a separate "slsh" package you
    will need to install:

      apt-get install slsh

1. Choose an installation location for JED. JED is distributed in a
   TREE structure:

     $JED_ROOT/
     $JED_ROOT/src
     $JED_ROOT/info
     $JED_ROOT/doc
     $JED_ROOT/lib
     $JED_ROOT/bin

   Here JED_ROOT can be anything (e.g., /usr/local/jed).  It must be
   specified in the Makefile of the src subdirectory.  It is important
   that the subdirectories under $JED_ROOT remain intact.  An
   environment variable called `JED_ROOT' can also be created to over
   ride the value compiled with the executable.

3. Build JED.

      ./configure --prefix=/usr/local

   This assumes that you want it installed with JED_ROOT equal to
   /usr/local/jed/, with the main jed executable installed in /usr/local/bin/.
   This step creates the necessary Makefiles.  
   
      * Note: If you have the slang library installed in a
              non-standard location, you may have to tell configure
	      where to look, e.g., 
	      
	         ./configure --prefix=/usr/local --with-slang=/goodies/lib

              For more options, run `./configure --help`

      * Note: On CYGWIN, make sure the libslang2.dll in your PATH,
              otherwise jed will not run, nor will the chkslang program.

      * Note: On Linux systems, JED may be compiled to take advantage
	      of the GPM mouse server.  See the mouse section in
	      src/Makefile for enabling this.

      * Note: If you are building jed on a system that uses more than
	      one architecture, then before running make, define an
	      environment variable called ARCH whose value specifies
	      the system, e.g., sun4, solaris, etc.

   Now type `make' at the shell prompt.  If you have X windows and you
   would like to create 'xjed', additionally run 'make xjed'.  If all
   goes well install it with `make install'.

   JED comes with a highlighting recursive grep program called rgrep.
   Use `make rgrep` to build it.
   
4. By default, when JED starts up, it will load some files out of
   $JED_ROOT/lib then it will look for the file .jedrc in the user's
   home directory.  If it does not find it, it will load the default
   file jed.rc from $JED_ROOT/lib.
   
   In fact, the user is encouraged to copy jed.rc to $HOME/.jedrc and
   make personal changes there.  The $JED_ROOT/lib/jed.rc file should
   be regarded as a template for .jedrc and should not be changed.
   The default editor emulation is specified by the
   _Jed_Default_Emulation variable, which defaults to "emacs".

   Site specific customization should be placed in /etc/jed.conf or
   more generally in $prefix/etc/jed.conf. An example jed.conf file
   may be found in the lib subdirectory.  Among other things, it may
   be used change many of the defaults on a system-wide basis.  For
   instance, many Unix users may not want emacs bindings and may
   prefer something like Borland's IDE keybindings.  It is in this
   file where such defaults may be made.  See the sample file for more
   details.
   
   For more information about customizing jed on a site-wide basis,
   read the INSTALL file.

5. Optional but highly recommended: preparse the S-Lang files.  This
   is done by running JED as:
     
         # jed -batch -n -l preparse.sl

   This creates pre-parsed *.slc files that load quicker than *.sl
   files. If this step fails to work for some reason, JED is probably
   not properly installed.  Note that the bytecodes that are stored in
   the preparsed files (*.slc) may depend upon the version of the
   slang library that was used.  This is particularly relevant if jed
   is dynamically linked to the slang library and for some reason you
   upgrade the library.  If you do this, then immediately after
   installing a new version of the slang library, run the command
   `touch *.sl' on all the .sl files in the $JED_ROOT/lib directory.
   See the release notes (changes.txt) that are distributed with the
   slang library to see if any of the byte-codes have changed.

6. New releases will be announced to the jed mailing lists as well
   as the newsgroups comp.editors and alt.lang.s-lang.  See
   <http://www.jedsoft.org/jed/> for more information about
   the mailing lists.  Additional information may be found at
   <http://www.jedsoft.org/slang/>.

7. That's it.  Enjoy.
