Initial check in dumb 0.9.2 - has a few usages of floating point that should

be rewritten to fixed point. seems to compile cleanly for iriver.

+# Please edit this file to control the playback quality for 'dumbplay'. Note
+# that this does not affect DUMB when you use it in your own programs; you
+# need to borrow some code from the example program in order to get that to
+# happen.
+
+# dumb_resampling_quality can be 0 for aliasing, 1 for linear interpolation
+# or 2 for cubic interpolation. See docs/dumb.txt for details on what these
+# terms mean.

+# dumb_it_max_to_mix is the maximum number of samples DUMB will render at a
+# time. See docs/dumb.txt for a more detailed description.

+# Increase buffer_size to combat stuttering.
+
+# The music module will be rendered at the sampling frequency specified by
+# sound_freq. This variable is also used by Allegro for initialising the
+# sound hardware.
+
+# buffer_size and sound_freq are passed directly to al_start_duh(). See this
+# function's description in docs/dumb.txt for information about how to use
+# these variables.
+
+# You can ignore the quality variable. Allegro uses it when relaying the
+# audio stream to the sound card. Only a masochist would set it lower than 2;
+# if your computer is powerful enough to run DUMB, it is powerful enough to
+# use this setting with Allegro.
+
+# For best results, choose a value for sound_freq that your sound card can do
+# exactly. See Allegro's docs, "Standard config variables", for details. If
+# you do not choose an exact value, Allegro will round it to the nearest
+# value it can do; then when DUMB plays the stream at a sampling frequency of
+# sound_freq, Allegro will have to resample it. Allegro's 'quality = 2'
+# setting is only comparable with DUMB's 'dumb_resampling_quality = 1'
+# setting. Therefore, in order to appreciate DUMB's cubic resampler fully,
+# you will need to make sure Allegro doesn't do any resampling, by choosing
+# an exact value for sound_freq.
