22# to assume all libraries will end up in lib. Replace any (sane) instances
23# where lib is named directly with $(get_libdir) if possible.

918# strings <pdv archive> | grep lseek
919# strace -elseek <pdv archive>
920# basically look for the first lseek command (we do the strings/grep because
921# sometimes the function call is _llseek or something) and steal the 2nd
922# parameter. here is an example:
923# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
924# lseek
925# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
