+   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
