#   NAME
#   docDos2Unix - copy files from Dos to Unix (counterpart of docUnix2Dos)
# 
#   SYNOPSIS
#   docDos2Unix  [ <target_dir> ]
# 
#   DESCRIPTION
#   
#   In the following, a "DOS" directory is a UNIX directory containing
#   files which have been modified on a PC and copied to UNIX with 'mkdir'
#   and 'cp' commands. These files must have been transfered from UNIX
#   to DOS using docUnix2dos.
#
#   This command must be executed from the "DOS" directory.
#   The default target directory is the one from which the docUnix2Dos
#   command has been executed.
# 
#   docDos2Unix copy files from the current "DOS" directory to <target_dir> 
#   and rename them with their UNIX name. Note that <target_dir> must not 
#   have a final '/'.
#
#   To copy a DOS directory back to the original UNIX directory from an 
#   ENVIZEX terminal, do the following  steps:
#
#   1. Create the "DOS" directory on UNIX
#      mkdir $HOME/<dos_dir>
#   2. Copy the floppy disk directory <dir> to the "DOS" directory:
#      cp $HOME/floppy/<dir>/* $HOME/<dos_dir>
#   3. Copy the contents of the files and rename them:
#      docDos2Unix
#   
#
#   FILES
#   * in current floppy directory  read
#   
#
#   ENVIRONMENT
#
#   RETURN VALUES
#
#   CAUTIONS
#
#   A file which has been created on the floppy (i.e. which did'nt exist on
#   UNIX) is copied back as it is, using 'cp' naming conventions.
#
#   This command executed without any argument will overwrite the original 
#   files.
