The MODULEF library management commands are supplied with the source code and are found in directory $MR/ascii/com.util ( Variable MR has the same value as during installation.).
Before using these commands, it is necessary to make sure that your site is configured correctly, and that these commands are adapted to your machine.
Warning: We assume in this section that we are working with shell csh. However, other shells ( sh, ksh, ...) can of course also be used.
It is necessary for all MODULEF users to define the following variables in file .cshrc( or .profile for shell sh.):
To help the reader initializing the above variables, he/she should consult the variables defined during the installation of MODULEF, found in file $MR/make/Install$MM.
All these variables can, for example, be declared in file modulef.csh and stored in directory $MR/ascii/com.util. Consequently, all persons wishing to use the MODULEF environment need only add the following line in file .cshrc in their home directory:
source absolute path/ ascii/com.util/modulef.csh
Please consult Appendix H for an example of file modulef.csh
The existence of these files are indispensable as they are used by the library management commands.
These two files are created by the installation Makefile found in directory
 $MR/make/Install$MM. If these two files have not been created during installation, enter the following commands:
B$ cd $MR/make/Install$MM
B$ make gestion
Read access to the source libraries ( batc bihm ... vis3) and their contents is given to all. On the other hand, write access can be protected by choosing one of the following options:
This protection is assigned by entering the following commands:
B$ cd $ms
B$ chmod -R a-w *
This protection is assigned by entering the following command:
B$ cd $ms
B$ chmod -R gu=rw *
The disadvantage (or advantage) of the first proposition is that only the owner of the account where the library is found may use the management commands to modify, compile or delete an element in the library.
On the other hand, this restriction disappears in the second proposition. Everybody belonging to the same group as MODULEF can modify the library by using (or not) the library management commands!
Having created your environment, we can now go ahead and adapt the management tools to your machine.
Some of the commands you received are not only machine-dependent, but also dependent on your personal choices (text editor, ...). It is therefore necessary to adapt the following commands to your site:
ar_ and voir.
Command voir is used to visualize source files. In this command, the variable EDITOR needs to be initialized.
The command ar_ is an improved archive command. To adapt it to your site, it suffices to delete command ranlib if it is not defined on your machine (for example Silicon Graphics).
