map< string, string > Tools::Split	(	std::string &	opt,
		bool	allow = false
	)

Splits a string into a filename and command line arguments, like:

file.txt arg1=argument1 arg2="argument 2" arg3="argument \"3""

'file.txt' will be returned on opt, the arguments will be returned in the returned map.

If the returned file name is empty, an error has occured: If the map is also empty the file name was empty, if the map has one entry then for this entry the equal sign was missing.
