* dirin: directory of input pages
* reduction: 1 (full res) or 2 (half-res)
* thresh: 0.80 is a reasonable compromise between accuracy
* and number of classes, for characters
* weight: 0.6 seems to work reasonably with thresh = 0.8.
* rootname: used for naming the two output files (templates
* and c.c. data)
* firstpage: <optional> 0-based; default is 0
* npages: <optional> use 0 for all pages; default is 0
