Detailed Description

specification and retreiving of non standard options on the command line.

example:

• command line: myappli --input data.txt --val 5 --no-reco
• note: --no-reco is the negation or --reco

Source code for parsing these options:

   char* input_file  = null;
   int   value = 1;
   bool reco_mode = false;

   UOption options[] = {
     {"in","put", UOption::Arg(input_file)}, // "in" is mandatory, "put" is optionnal
     {"value","", UOption::Arg(value)},      // "value" is mandatory, no optionnal part
     {"reco","",  UOption::Arg(reco_mode)},  
     {null}  // must be NULL terminated !!
   };

   // changes the values of variables 'input_file', 'value' and 'reco_mode'
   // if the corresponding options are specified in the command line

   UConf conf(argc, argv, options);
   UAppli appli(conf);
   ...
