# x11docker/kaptain
#
# Kaptain is a universal graphical front-end for command line programs. 
# It works on linux/UNIX platforms whereever Qt is available. 
# Release 0.73 is using qmake and is compatible with Qt 4.
#
# Someone writes a simple script (so called grammar) which describes 
# the possible arguments for a command line program and Kaptain 
# brings up a friendly dialog to the user to set up the command line.

# Example use with x11docker (https://github.com/mviereck/x11docker):
#   x11docker --hostdisplay --clipboard --share YOURKAPTNFILE -- x11docker/kaptain YOURKAPTNFILE
