I've looked through it and it is quite well done. Could we add
it to the grass-addons repository?
a couple of minor notes-
* consider moving the temp file creation until after all the
parsing checks are done, so that they are only generated when
we know the module is going to run and empty files are not
* always "quote" filename $VARIABLES, or else the script will
break on MS Windows where path names commonly have spaces in
* did you try the geology/strike* symbols before making your own?
were they deficient for some reason? (too long bases for the
task, or ..?) [no problem, just like feedback if they could be
* consider advertising it in the geology + atmospheric science
field of study sections in the GRASS wiki:
* besides left,right, consider a "both" side of line option.

the problem of line styles is still not completely solved,
hopefully we can do something with that in grass7, but this has
been a missing functionality for a long time- so thanks!
ps- I just noticed the collection of new symbols by Martin
Povolny. lots of them, great. :)
