* Full relocation (No "-fpic" or similiar needed)
* Every kind of section in an ELF file (E.g. ARM unwind information for C++ exceptions)
* Executable files up to 16MB in size (can be larger if no relocations after 0xFFFFFF)
* Various flags and extra information about the executable:
** Maximum and minimum version and revision of ndless needed to run (https://cloud.githubusercontent.com/assets/1622084/3762493/a7ed3a22-1897-11e4-8d94-77f82ecfa239.png)
** HW types (Clickpad/Touchpad/CX/CM) supported
** Application name, version, author, description (these can be viewed by holding down the "catalog" key when opening the executable: https://cloud.githubusercontent.com/assets/1622084/3762440/0d70af1a-1897-11e4-860b-cf07b6521634.png)

The main header file (https://github.com/ndless-nspire/Ndless/blob/master/ndless-sdk/include/zehn.h) contains everything needed to parse a Zehn file.
<td> hackspire.org is now the main domain name
The Zehn header (identified by ZEHN_SIGNATURE) may be everywhere (4-byte aligned) in the first 4KiB if the file starts with "PRG\0" to support backwards-compatibility.

The "genzehn" tool (https://github.com/ndless-nspire/Ndless/blob/master/ndless-sdk/toolchain/genzehn/genzehn.cpp) converts ELF files with embedded relocation info (needs to be linked with "--emit-relocs") to relocatable Zehn files. Run "genzehn --help" to get version and usage information.
<td> Hackspire is back up, now maintained by [[User:Jim Bauwens|Jim Bauwens]]
For basic conversion it's sufficient to only specify "--input input.elf" and "--output output.tns". The resulting executable will open on every version of OS, ndless and type of hardware and the version will be 1.

The "make-prg" tool (https://github.com/ndless-nspire/Ndless/blob/master/ndless-sdk/bin/make-prg) adds zehn_loader.tns at the top of the file, so that older versions of ndless without native support for Zehn. "zehn_loader.tns" is also used to boostrap ndless_resources, which is a Zehn file itself. It doesn't support any of the flags, so your executable may be executed on unsupported hardware or significantly too old OS versions! To use it, execute "make-prg <input> <output>".

It compiles zehn_loader.tns if needed.
