can someone shed some light on this scripting language?

i came across this in a photoshop plug.

there are a bunch of .fsl files inside of a masked zip file
and these files have script functions. that i can't figure out how to manipulate.

i'm assuming the 'sl' part of 'fsl' is perhaps 'script language'? just a guess

here's a snippet of some script code:

C p2h-get-full-name ()
6 27
12 00 05 03 0b 00 10 04 04 10 05 05 0b 00 10 04 
06 10 05 07 0b 00 10 05 08 0c 05 
D p2h-get-release
D "_"
D p2h-get-version
D " "
D p2h-get-name
D string-append
D p2h-get-full-name
C () ()
2 10
12 00 04 03 11 06 04 04 04 0d 
C p2h-get-registration-string (pvec)
4 27
12 01 07 00 02 10 05 03 0b 01 02 00 14 04 04 10 
05 05 0c 01 04 06 10 05 05 0c 01 
D sg-is-unlocked?
D "REGISTERED"
D gls
D "NOT REGISTERED"
D p2h-get-registration-string

anyway, if someone knows what this is and how to play with it please reply. thanks

EDIT:

if anyone wants to take a look at this interesting method of protection, here's the file:

Hello man,

FSL is a comprehensive library of image analysis and statistical tools.FSL is written mainly by members of the Analysis Group (FMRIB at Oxford/UK).

You need an FSL compiler along with other tools. Here's a list:

Why you need to edit those files?

perhaps i don't, but the dll files that accompany this compilation of files doesn't reveal anything at first glance. then i found these and figured that it may be manipulated by changing these files. just a hunch.

For me this looks like an excellent Software Protection.
Extracting the critical Part of Key-Verification into a wired type of scripting-language that nobody, except a couple of Oxford Scientists, understands. ^^
Thats even better than developing your "own" Virtual Machine.

nah this scripting language looks to be quite easy to understand
