__ifstool__ is a portable open-source reimplementation of QNX's [mkifs](https://www.qnx.com/developers/docs/8.0/com.qnx.doc.neutrino.utilities/topic/m/mkifs.html), that is able to pack, unpack and analyze x86_64 BIOS and UEFI QNX IFS images, compressed or not, bootable or not, using the same script file-based syntax as mkifs. Most of the mkifs options are supported. Can be built as a **native QNX tool**. Already used in production in some places.

The goal was to turn QNX8 into a self-hosted platform. Since QNX no longer supplies a native toolchain (compiler, linker, binary utilities, IFS utilities) __ifstool__, when used along with the GNU linker (cf. [QNX8 native binutils](listing.php?repname=QNX%208.QNX8%20native%20binutils)) can be used as a drop-in replacement.
