Bugs in libdmtx
-----------------------------------------------------------------

1. libdtmx - Core Library
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

While regular encoder works fine, the optimizer feature (--best)
still occasionally generates codeword sequences that are not 100%
legal according to the ISO specification.  Everything still
appears to decode properly, but until I have time to go through
every corner case and validate the behavior this will be treated
as an experimental feature.  For now dmtxwrite will encode using
a straight ASCII scheme by default.

Data Mosaic encoding doesn't produce output for certain sizes:

   $ echo -n foo | dmtxwrite -M    <-- works
   $ echo -n fooo | dmtxwrite -M   <-- doesn't work
   $ echo -n foooo | dmtxwrite -M  <-- works


2. dmtxread
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

The follow options are considered experimental:
  -M,  --mosaic              interpret as Data Mosaic barcodes

When using --verbose output, the Data Codeword capacity is often
reported incorrectly.


3. dmtxwrite
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

The follow options are considered experimental:
  -eb, --encodation=b        best encodation (beta only)

The follow options are not implemented yet:
  -ef, --encodation=f        fast encodation
  -c,  --color=COLOR         barcode color
  -b,  --bgcolor=COLOR       background color
  -r,  --rotate=DEGREES      rotation angle
  -M,  --mosaic              create Data Mosaic barcode


4. Test Programs
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

gltest:
  * No known issues

simpletest:
  * No known issues

unittest:
  * No known issues


5. Wrappers
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

libdmtx-php:
  * Does not compile with recent libdmtx versions (needs update)


6. Scripts in the script directory
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

The check_headers.pl script verifies that every function has
a correctly-formed header comment.  But the test condition is
currently pretty simple, and does not test the first function
appearing in each file.
