Installation:
  rpms exists.
  It's in debian. (apt-get install tla).
  source tarball: download, untar, make build dir, confiugre && make test && make install.

Then...
Setup your global identity for arch:
 tla my-id "Robert Collins <robertc@robertcollins.net>"

create revision library (Optional, is a performance tuning tool).
 mkdir -p ~/arch/revisionlibrary
 tla my-revision-library ~/arch/revisionlibrary

create somewhere to store your archives, and your mirrors of remote archives.
 mkdir -p ~/arch/archives

create a repository therein. Note that the target dir (second parameter) must not exist.
 tla make-archive john.doe@example.com--2003 ~/arch/john.doe@example.com--2003
 (reusing the archive name ^^here^^  on the directory name allows easy identification later.)

create your sources - untar, cvs checkout etc.
 mkdir -p ~/source/lca-fixit/source-tree
 cd 
 vim README
   put random content in this file.
 vim README.tagged
   put random content, AND an arch tag line:
   # Don't edit the next two lines.
   # arch-tag: <ESC>:r /proc/sys/kernel/random/uuid
   #

setup the tree to use arch
 tla init-tree john.doe@example.com--2003/example--mainline--1.0

naming methods - source / binaries / junk classification rules. Sane defaults nowadays.
 set tagline

demonstrate tree-lint and the tagged vs explicit file details.
 tla tree-lint - note the warning on README but not README.tagged.
manually add README to tla: (You can automate this via a small idiom (coming up in a soon to be done whitepaper...)
 tla add README
 
import the code, creating the branch on the fly.
 tla import -S

checkout the code somewhere else
 cd ..
 tla get john.doe@example.com--2003/example--mainline
  (note the automatic highest version  retrieval).
