.SS "FILE FORMATS"
In general, each file format starts with an ASCII header followed by
ASCII or binary data.  The ASCII header starts with a magic number, and can be
followed with any amount of white space (blanks, `\\t' (tab),
`\\n' (newline), `\\r' (carriage return)) and/or
comments lines (lines starting with "#").  Following this white space,
each format has a varying amount of header information in ASCII.
This ASCII header information is separated by blanks and newlines.
The data follows this ASCII header information.  Note: if the data is
in binary, one (and only one) newline
.B must
follow the last component of ASCII header information.
If the data is ASCII, components of the data are separated with
blanks and/or newlines.

.IR "p1 p2 p3" \|.\|.\|.

where CBK is the magic number, X.X is the revision number,
.I "<white space>" 
is white space and/or 
comment lines, 
.I N 
is the number of codewords the file contains,     
.I dim 
is the number of components each codeword contains (vector     
dimension), 
.I wij 
is the jth component of the ith codeword, and 
.I pi 
is
the probability of the ith codeword.
.I N 
and 
.I dim 
are integers. 
.I wij 
and 
.I pi 
are floats.
.I N 
and 
.I dim 
are stored in ASCII, 
.I wij 
and 
.I pi 
as binary (4 bytes, MSB first).
No white space may exist between the 
.IR wij "'s" 
or the 
.IR pi "'s."
