well I have some good news.

I have made it compatible with the BMS scripting language so people don't need to learn 1000 languages and then it's a good language.
, s8 d* C2 ?/ ?$ R/ Qobviously the BMS support has been enhanced so it's possible to use XOR, rot13, zlib/deflate, lzo, lzss plus various new operator in the "math" command (and, or, xor, complement, not, shift and modulus) and some other things like choosing the desired endianness.
5 E' ?+ r7 S( I5 N0 k' E* Mthen the input BMS script no longer needs the semicolon ';' and the file number which are now optional. " g# V& t+ c- @2 w. d
7 D5 C t" C+ d# J Ynote that the BMS guide available on http://wiki.xentax.com/index.php/BMS doesn't report some additional fields which instead already exists like the GetCT, ComType and ReverseLong or some internals variables like EXTRCNT so I have tried to find and add also these ones. ) B' b( E" i3 j6 m9 D
. {/ j9 E* |. C4 ]: Cabout the new commands, the following is an example of BMS script for the game Outcry (you can call it outcry.bms or outcry.txt or as you want):

obviously it needs to be tested more because 2 days are not enough for a project like this which is not so basic so anyone is invited to test it and suggest new features.

if you know the size of the structure or where is located the particular value you are searching (for example some file formats have a 32bit number in the last 4 bytes which has the offset where are located the other file structures) you could use something like the following: # J- T0 G- r9 h
3 O' q7 H+ R ?- }% _- ?Code:get OFFSET asize ( i9 o1 d( i3 A' {) l( r, M1 w
math OFFSET -= 4
% v* f3 k* s: l1 pgoto OFFSET _, \' Q% \! `0 S
get OFFSET long % g& Q& u# P& c
goto OFFSET
* x H/ y0 c. I/ U..."asize" is not available in the BMS guide but is supported by both multiex and my tool, it contains the total size of the file.
3 V7 |/ b, M+ E3 L; fanyway tell me a file format which has the file name table at the end, it's good to make various exercises for testing the BMS language and where is possible to enhance it. $ x/ v* J6 w. l: g3 x- Y

oh and about the "repacking" question, no it will be not supported
