- * The following options apply only to the concat type:
- *    <begin-date> is the earliest date to check for uncompressed revisions
- *    <end-date> is the latest revision date to compress
- *    <chunk-size> is the maximum number of revisions in a concat chunk
- *    <max-factor> is the maximum ratio of compressed chunk bytes to uncompressed avg. revision bytes
- *    <factor-threshold> is a minimum number of KB, where <max-factor> cuts in
+ * Options are:
+ *  -t <type>           set compression type to either:
