LGR_UGGA_File.name_date_formats = ((re.compile('^gga(\\d{2}[A-Za-z]{3}\\d{4})_'), '%d%b%Y'), (re.compile('^gga_(\\d{4}-\\d{2}-\\d{2})_'), '%Y-%m-%d'))

The two ways the LGR software has named its files, matched on the name itself rather than looked up by software version, so a new version that keeps either style needs no change: gga01Apr2014_f0000.txt (904M, WBB 2014-2016) and gga_2015-11-17_f0000.txt (2f90039, cf32204).
