ArgumentParser sofa::helper::parse ( const std::string &  helpstr = "",

Parse a command line.

Parameters:
helpstr General help message
hs short name for help
hl long name for help This method frees the programmer from explicitly creating an ArgumentParser, which makes the program (hopefully) more readable. Using this method, the ArgumentParser is transparently created, it receives and processes the arguments, then it is destroyed.
