Jason, Cathy,

I changed the POD description to the following in CVS:



This is a parser and event-generator for AXT format reports.  BLASTZ
reports (Schwartz et al,(2003) Genome Research, 13:103-107) are normally
in LAV format but are commonly post-processed to AXT format; precomputed
BLASTZ reports, such as those found in the UCSC Genome
Browser, are in AXT format.   This parser will also parse any
AXT format produced from any lav report and directly out of BLAT.
