Libarchive is an archive library for FreeBSD developed by TimKientzle. This project's goal is to enhance it as far as possible. The original project description can be found on the FreeBSD page at Google Summer of Code 2008.
It truly has been a long time I last made updates here … GSOC finished, despite I reached only a few of my original goals. Well, work will continue, not under Google's lead, and on a free time basis. Most likely, this site won't be updated anymore. Check the source repositories for updates.
Did some more features on the ZIP writer and testing. Consequently I also had to fix some bugs … Now turning on the compression support and support for non-regular file entries. Also must keep an eye on the next goal, most likely the PAX frontend.
Implemented a basic ZIP writer without compression support and CRC computation. Now I must definitely go for some testing … Last week on Thursday 11th, there was also a meetup at Google Zurich. It was good to see some real faces behind the project, there were also some nice presentations and discussions. What a pity Google didn't let us have a look at their server room … ;)
Working on the ZIP writer and dealing with:
Tired for now, tomorrow is another day …
I set up:
I bought a PDF of “C in a Nutshell” to refresh my C programming skills and have a good reference. Also I made some exercises with GNU Autotools to understand it better. Also I had a lot to do with my master thesis, so I spend a lot of time there … :\
This week coding also started for me :D
Finally found some time again to work on my project. I setup the wiki pages, so now I'm almost ready to go. Our studies will finish May 30, one week after the official coding phase start.

ZIP reader is already there and the ZIP writer can lean it's code on the existing CPIO writer.
Official .ZIP File Format Specification is available from PKWARE. The Info-ZIP software specifies some of the extensions mentioned by PKWARE.
