** Class to encapsulate the typical C-style commandline definition.
|
||
** A Cmdline object takes the typical `int argc, int** argv` and _copies_
|
||
** the referred data into a vector of strings. Thus `Cmdline` is a way to
|
||
** express explicitly on APIs that we are consuming commandline contents,
|
||
** and, moreover, it offers a way more sane interface to deal with those.
