libjel -- JPEG Embedding Library
==========
This library supplies an API for embedding and extracting bit strings
into / from JPEG images. The library uses heavily quantized frequency
components to provide storage that is stabilized by the JPEG
compression process. As a result, embedded bit strings are preserved
under a number of different transformations, including transcoding to
higher quality, DC or low frequency shifts in pixel value, and limited
image rescaling.
Please see *"TRIST: Circumventing Censorship with
Transcoding-Resistant Image Steganography"*
for a detailed explanation on what this tool does and how it does it.

General Compilation
-------------------
Prepare the raw git repository first and generate configure and Makefile:
```
autoreconf -fvi
./configure --enable-silent-rules
```
To compile manually:
```
make
```
Debian
------
To make a Debian package:
```
dpkg-buildpackage -b -us -uc
```
