The only maintained project is jhalfs. It is available for download in two formats:
This is the lastest released jhalfs building framework. A tarball of the most recent version is available from the stable jhalfs directory. It can also be checked out from the subversion repository:
svn co svn://svn.linuxfromscratch.org/ALFS/jhalfs/tags/2.4 jhalfs-2.4
The current development version can only be obtained from the subversion repository:
svn co svn://svn.linuxfromscratch.org/ALFS/jhalfs/trunk jhalfs-dev
Packages required for jhalfs
Before it can parse the LFS book for commands, jhalfs needs to have a local copy of the book's XML source. Currently, jhalfs relies on Subversion to ensure that it has the most up-to-date version of the LFS Book. There are build instructions in BLFS.
