[Tilesathome] Easy to install chrooted T at H client

[L.Drolez]

Hi !

Here's my 1st attempt to provide an easy to install/use T at H client:

http://ldrolez.free.fr/software/tilesathome-chroot-0.1_080331.tgz

To use it:
- decompress the archive to /yourpath
- copy /yourpath/home/tah/tilesAtHome/authentication.conf.example
  to authentication.conf, and edit the file to provide your upload
  credentials.
Then:
- run 'chroot /yourpath ./runtah' , to launch the regular client.
  In that case, 'touch /yourpath/home/tah/tilesAtHome/stopfile.txt'
  to stop the client loop.
- or run 'chroot /yourpath ./runtahlz1 X Y' to start the 1st pass
  of a lowzoom rendering
- and run 'chroot /yourpath ./runtahlz2 X Y' to start the 2nd pass.

You can edit runtah.conf to set the max memory used by the T at H client.
This chroot is based on a Debian Etch, and I use it without any problems.
The lowzoom scripts are not perfect but work fairly well.

Suggestions and flames both welcome !

Enjoy,

  Ludovic.
