/**
@brief Define a standard CPL recipe
@param RECIPE_NAME The name as an identifier
@param RECIPE_VERSION The binary version number
@param RECIPE_FILL_PARAMS A function call to fill the recipe parameterlist.
Must evaluate to zero if and only if successful
@param RECIPE_AUTHOR The author as a string literal
@param RECIPE_YEAR The copyright year as a string literal
@param RECIPE_SYNOPSIS The synopsis as a string literal
@param RECIPE_DESCRIPTION The man-page as a string literal
A CPL-based pipeline recipe may use this macro to define its four mandatory
functions: cpl_plugin_get_info(), <recipe>_create(), <recipe>_exec() and
<recipe>_destroy(), as well as declaring the actual data reduction
function, <recipe>() as
@code
static int <recipe>(cpl_frameset *, const cpl_parameterlist *);
@endcode
This may be done by defining a pipeline specific macro, e.g. in
mypipe_recipe.h:
@code
#define MYPIPE_RECIPE_DEFINE(NAME, FILL_PARAMS_FUNC, SYNOPSIS, DESCRIPTION) \
UVES_IRPLIB_RECIPE_DEFINE(NAME, MYPIPE_BINARY_VERSION, \
FILL_PARAMS_FUNC(recipe->parameters), \
"Firstname Lastname", "2002, 2003, 2005", SYNOPSIS, DESCRIPTION) \
@endcode
- and then by invoking this macro in each recipe:
@code
#include "mypipe_recipe.h"
MYPIPE_RECIPE_DEFINE(naco_img_dark,
naco_img_dark_fill_parameterlist,
"Dark recipe",
"naco_img_dark -- NACO imaging dark recipe.\n"
" ... recipe man-page\n")
@endcode
where naco_img_dark_fill_parameterlist() is a recipe specific function, that
takes an empty parameterlist and fills it with those parameters that the
recipe supports.
