# OVERVIEW
#
# pykaraoke_mini is a frontend for the pycdg and pympg karaoke
# players. It is similar to pykaraoke.py, but it is designed for use
# on small portable devices rather than PC's. In particular, it could
# be useful on any device lacking a keyboard and mouse.
#
# It presents a scrolling list of songs to choose from, sorted by
# title, artist, or filename. It works within the same pygame window
# used to render the karaoke songs themselves, so the scrolling
# interface is not available while a song is being performed. The
# biggest strength of pykaraoke_mini is that it does not rely on a
# keyboard or a windowing interface, so it is ideal for use with a
# joystick or even an IR remote control in a bar.
#
# Unlike pykaraoke, pykaraoke_mini does not store a database of song
# files, nor does it search around through different folders to find
# your song files. Instead, it is your responsibility to build a
# titles file, which is a text file that contains one line per each
# song. Each line should be of the form:
#
# filename <tab> title <tab> artist
#
# You can include international characters by encoding the file in
# UTF-8. All three of these fields will be presented to the user in
# the scrolling list. The filename is assumed to be relative to the
# catalog file itself.
#
# If you like, you can maintain multiple different catalog files of
# this form, which will allow you to run pykaraoke_mini with different
# subsets of your song files. Each file should be named titles.txt,
# or some variant on titles*.txt, such as titles_mysubdir.txt.
#
# While navigating the scrolling menu, the following keys are available:
# up / down : scroll through the list. Hold the button down to
# scroll very rapidly.
# pageup / pagedown : scroll a page at a time.
# enter : select the highlighted song for performance.
# tab : change the sort mode between title, artist, and filename.
# The current sort key is displayed first for each file.
# + / - : enlarge or reduce the font scale. This also affects the
# font scale when a MIDI file is selected (but does not affect CDG or
# MPG files).
# a-z : search for a song beginning with the indicated letter. If you
# type multiple letters, search for a song beginning with the string
# you type.
