// -------------------------------------------------------------
// History

// 2014-07-02: Conversion of the original tool written in X11-Basic
// (version A-00-20140212), with the help of
// x11-basic_to_mbim.vim, a little ad hoc tool written in Vim.
// 2014-07-22: Fix: typo in 'wtCls'.
// 2015-02-04: Some changes before publishing.

// -------------------------------------------------------------
// XXX TODO 

// 2014-07-03:
// check and improve indentation
// check the coherence of wtCr and wtDoCr: 
// wtCr should be mandatory, and wtDoCr can be removed
// 2014-03-31:
// scroll, pause
