+perl-Set-IntSpan   Manages sets of integers
+
+Set::IntSpan manages sets of integers. It is optimized for sets that
+have long runs of consecutive integers. These arise, for example, in 
+.newsrc files, which maintain lists of articles:
+
+alt.foo: 1-21,28,31
+alt.bar: 1-14192,14194,14196-14221
+
+A run of consecutive integers is also called a span.
+
+Sets are stored internally in a run-length coded form. This provides
+for both compact storage and efficient computation. In particular, set
+operations can be performed directly on the encoded representation.
