 * Preferences
 *

 * It uses a simple name=value syntax, with preferences separated by groups.
 * Groupnames are delineated with '[' and ']'.

# Note -- do not use '"'s around strings, they will be treated as part
# of the string.  Also be sure to use a double '\' in Windows filenames,

# String values must be in UTF8.
