Mostly, std::regexp can be used as a drop-in replacement. Note: unfortunately ECMA regexps do not support lookbehind assertions. This lookbehind is necesary here because we want to allow parsing values from strings with additional content, which means we need explicitly to exclude mismatches due to invalid syntax. We can work around that issue like "either line start, or *not* one of these characters. Alternatively we could consider to make the match more rigid, i.e we would require the string to conain *only* the timecode spec to be parsed.

/** @file cmdline.hpp

** 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.
