RAR - UNRAR Question

[donate]

ioftpd.ini:
unrar = EXEC ..\iozs\UnRAR.exe e
rar = EXEC ..\iozs\RAR.exe a

usage now:
site unrar $current_path\packed.rar $current_path\
site rar -m0 -v15000 -vn $current_path\pack.rar $current_path\source.file

( $current_path = Full Windows Path C:\ioftpd\.... )

THIS WORKS ^



But i want:

unrar = EXEC ..\iozs\UnRAR.exe e $file $destination
so:
site unrar packed.rar (this would extract in same dir as packed.rar)
or:
site unrar packed.rar /testdir/extract/here



rar = EXEC ..\iozs\RAR.exe a $m $v -vn $destination $source
(vn = old volume style)

so:
site rar 0 15000 pack.rar source.file


Anyone has any idea how this can be done?
With ioFTPD..... if not, WarC?



Thanks in advance
