+lttoolbox is a toolbox for lexical processing, morphological analysis
+and generation of words. Analysis is the process of splitting a word
+(e.g., cats) into its lemma 'cat' and the grammatical information
+<n><pl>. Generation is the opposite process.
+
+The package is split into three programs: lt-comp, the compiler;
+lt-proc, the processor; and lt-expand, which generates all possible
+mappings between surface forms and lexical forms in the dictionary.
