+/* ######################################################################
+
+ Command Line Class - Sophisticated command line parser
+
+ This class provides a unified command line parser/option handliner/
+ configuration mechanism. It allows the caller to specify the option
+ set and map the option set into the configuration class or other
+ special functioning.
+
+ Filenames are stripped from the option stream and put into their
+ own array.
+
+ The argument descriptor array can be initialized as:
+
+ CommandLine::Args Args[] =
+ {{'q',"quiet","apt::get::quiet",CommandLine::IntLevel},
+ {0,0,0,0,0}};
+
+ The flags mean,
+ HasArg - Means the argument has a value
+ IntLevel - Means the argument is an integer level indication, the
+ following -qqqq (+3) -q5 (=5) -q=5 (=5) are valid
+ Boolean - Means it is true/false or yes/no.
+ -d (true) --no-d (false) --yes-d (true)
+ --long (true) --no-long (false) --yes-long (true)
+ -d=yes (true) -d=no (false) Words like enable, disable,
+ true false, yes no and on off are recognized in logical
+ places.
+ InvBoolean - Same as boolean but the case with no specified sense
+ (first case) is set to false.
+ ConfigFile - Means this flag should be interprited as the name of
+ a config file to read in at this point in option processing.
+ Implies HasArg.
+ The default, if the flags are 0 is to use Boolean
