+.SH NAME
+classes-format \- File format for word class definitions
+.SH SYNOPSIS
+.nf
+\fIclass\fP [\fIp\fP] \fIword1\fP \fIword2\fP ...
+.fi
+.SH DESCRIPTION
+Various programs dealing with word classes use this format to define
+the posssible expansions of classes and their respective probabilities.
+Each expansion appears on a separate line as in 
+the synopsis, where
+.I class
+names a word class,
+.I p
+gives the probability for the class expansion, and
+.I "word1 word2 ..."
+defines the word string that the class expands to.
+If 
+.I p
+is omitted it is assumed to be 1.
+(All expansion probabilities for a given class should sum to one,
+although this is not necessarily enforced by the software and would
+lead to improper models.)
+.PP
+Note that the concept of word class here is generalized to include
+``multi-words'', or phrases consisting of more than one word.
+All expansions must have at least one word.
+Certain models might impose more restrictive formats.
