Administrators can greatly simplify usage of commercial applications and custom utilities by providing wrappers that set up the required environment for complex applications; and can monitor usage of critical programs by creating a directory of wrappers, and placing this directory in the default command path.
The modules(1) application is a powerful example of an alternative method of providing similar functionality; but a simple systematic approach using a single script can provide this service. Here is a simple example shell script that can easily be expanded. I use a more expansive version to make access to over a hundred applications as simple for the user as executing a standard command such as ls(1): wrapper.
