;2 this file called by xcrystal_bent_theories to define the available 
;3 modules for bent crystal diffraction calculations. The reason of this 
;4 file is to facilitate the extension of modules for the embedded xop.
;5 xcrystal_bent_theories() is called by xop_defaults()

;7 the structure of this file is fixed: 15 comment lines (this text) and two
;8 lines for each module, the first one is the theory name and the second
;9 one corresponds to the binary module that computes it
