install [weborf]

Your first step is to download weborf's source code.
Then you will have to compile it.

Supported architectures

But weborf was succesfully compiled and executed on:

All architectures supported by Debian (including the ones with BSD and Hurd kernels)
Linux ARM
MacOsX (Snow Leopard) x86-64
MacOsX (Tiger) x86

To compile on opensolaris, it is necessary to:

Edit Makefile
Delete the lines beginning with CFLAGS and LDFLAGS
Uncomment CFLAGS and LDFLAGS for OpenSolaris (search for the OpenSolaris string, and they are right above it)
Save the Makefile
Compile as usual

If there are problems it is possible to report them, but don't expect to receive fast support.
