Current release: 1.3.5
________________________________________________________________
1.3.5 - fixed output options

- '-quiet' option no longer suppresses error messages
- when reading tag expression from sequence names (using the _XX convention) only the last occurrence
   of '_XX' is used.
- nexalign now consistently exits with a non-zero exit code in case of an error
- as a default basic mapping statistics are now printed to STDERR at the end of each run
- runtime is reported as a default
- nexalign reports the number of sequences mapping but not included in the output due to the '-u' parameter. 

________________________________________________________________
1.3.2 - fixed -u and input with sequence names. 

- '-u' option now works as expected: -u 10 will cause nexalign to report only
alignments for tags mapping 10 times or less, regardless of the number of 
databases used. 

- Nexalign now reads in both sequences and sequence names. To 'unique'
tags use the new -uniq option has to be used.  

- added -threads option - allows users to specify the number of threads used. 

- added -min-len and -max-len options.

- added -time option.
