First thing to do:  create the directories  data txt seq0 seq1 seq2 seq3...
and codi  using the command mkdir

Second: copy the file map.tar.gz  into the directory codi and then
uncompress it using 'gunzip map.tar.gz'and untar it using 'tar xvf
map.tar'

Third: copy the file .env_linux into your home directory, edit that
file, replacing the path binette by your own (in all environment variables)

Fourth: source that file .env_linux  and type the 
command cmi to compile mappings (cmi is just an alias that uses makegnu)

If you want more guidance on how to install and run MAPPINGS Ic, you
may look at the file hpldat.dat This file is also accessible once the
code is compiled by typing 'h' in the Main Menu.


SUMMARY: the useful files for a linux machine in order to recreate
MAPPINGS'environment are:

1- makegnu is to compile code in gnu fortran (linux environment),
code should be in dir: codi

2- sm.linux  is for supermongo (in HOME)

3- the file .emacs_linux will have to be rename to proper name if used

4- .env_linux is to have the MAPPINGS commands initialized (to be
located in HOME) must add at the end of the file .cshrc the following
line: source .env_linux The file .env_linux serves as a basis to
define essential environment variables when running the code
