+ 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.
