sfprint.c prints soundfile header stats
sfcreate.c creates soundfile headers in bsd/IRCAM style or NeXT style
sfextend.c extends the length of a soundfile, with a hole.
sfhedit.c edits information in a header.
sfshrink.c shrinks a soundfile to a given size


[RTcmix2.0 NOTE:  I believe these only work on NeXT/BSD/IRCAM soundfiles,
 not on aiff soundfiles.]
