maintenance. However, it may be more generally applied to any similar
application, and the details of the CPL code have been engineered in a
way to make the library portable and flexible, as well as minimising
external dependencies.

esorex
- Ebuilds: 1, Testing: 3.12.3-r1 Description:
EsoRex is the ESO Recipe Execution Tool. It can list, configure and
execute CPL-based recipes from the command line. One of the features
provided by the CPL is the ability to create data-reduction algorithms
that run as plugins (dynamic libraries). These are called recipes and
are one of the main aspects of the CPL data-reduction development
environment. As these recipes are dynamic libraries, it is not
possible to run them directly from the command line. However, ESO
provides several tools to do this, thus saving recipe developers the
need to write such an application themselves. One of these is GASGANO
(a GUI-based tool) and the other is EsoRex (which runs from the
command line.
