# .TYPE           command
# .NAME           install.sh
# .LANGUAGE       shell script
# .ENVIRONMENT    Unix Systems. Executable under SHELL and C-SHELL
# .COMMENTS       Installation procedure of the MIDAS system starting from
#                 scratch.
#                 
#                 Usage: install [options]
#                 
#                    options: are options for the "make" command. This option
#                             will be exported to all the directories of the
#                             installation procedure.
#			      Multiple definitions for keywords must be:
#				e.g.	CFLAGS=\"-O -g -I/usr/include\"
#			      to avoid quotes to be interpreted by the shell.
#
#                 The command will execute the following steps:
#
#                    - $MID_HOME/local/make_options is read if exists.
#		       It contains local options for "make" commands.
#                        
#		     - MIDAS is structured in "core" (all directories 
#			in file "core.cnf" are included in the installation).
#			and "packages" (optional, they are clasified in 
#			"applic", "stdred" and "contrib".) A package is 
#			selected for installation if it is marked with file
#			"SELECTED".
#
#                    - All the directories involved in the installation are
#                      cleaned by running "make options clean" command. 
#
#                    - Run "make options" in all the directories.
