-CONFIG FILE FORMAT
-----------------------------------------------------------------------
+Tailor's metadata
+=================
 
-Here's an example config file entry:
+To do its work, tailor needs some information about your source tree,
+such as the upstream repository URL and the current revision of the
+sources on your harddisk.
+
+In the simpler case, tailor keeps this information in a file called
+`tailor.info`, one for each tailored project, that is a very simple
+text document, with the following information, one per line:
+
+1. Upstream repository kind (either "cvs", "darcs" or "svn)
+2. Target repository kind (the same as above)
+3. The name of the "module" that's been tailored
+4. The URL of the upstream repository (that may not be an URL, for cvs...)
+5. The current revision, from the upstream point of view, of the sources
+
+This is everything tailor needs, to be able to keep going from where it
+left last time.
+
+Config file format
+------------------
+
+When your project is composed by multiple upstream modules, it is
+easier to collect such information in a single file. This is done by
+specifying the `--configfile` option with a file name as argument. In
+this case, tailor will read/write the above information from a
+standard Python dictionary stored in the given file. 
+
+The dictionary is keyed on the relative position of each project, and
+each entry carries the same information described above.
+
+Here's an example config file entry::
 
  {'plone/atcontenttypes': {'module': 'ATContentTypes',

                            'upstream_revision': '2004-11-24 19:42:06 by ctheune'}}
 
-The above represents one entry in a config file.  You can multiple entries,
-but be careful to make sure have an extra bracket on the first and last lines
-of the file. Here's an example with three entries to illustrate this:
-
- {'plone/atcontenttypes': {'module': 'ATContentTypes',
-                           'source_kind': 'cvs',
-                           'subdir': 'ATContentTypes',
-                           'target_kind': 'darcs',
-                           'upstream_repos': ':ext:cvs.sourceforge.net:/cvsroot/collective',
-                           'upstream_revision': '2004-11-24 19:42:06 by ctheune'},

 By convention, config files are named with the extension ".tailor", but this is
 not enforced.
 
-In the example above, 'plone/atcontenttypes' is a directory where the target source
-will be stored. The keys such 'module', 'source_kind', etc correspond to options
-of the same name. See the output of 'tailor.py' for more details.

+When using a config file, tailor will perform its job on each project

+See the output of tailor.py -h for some further tips. I will be more
+than happy to answer any doubt, question or suggestion you may have on
+it. I'm usually hanging as "lelit" on the IRC channel devoted to darcs
+on the freenode.net network. Do not hesitate to contact me either by
+email or chatting there.
