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