+#!/bin/bash
+
+#    $Id$
+
+# Fills the tracking file with versions of LFS packages taken from an
+# SVN repository, at either a given date or a given tag (argument $1).
+#------
+# Argument $1:
+# $1 contains a tag or a date, to indicate which version of the LFS book
+# to use. It may be empty, meaning to use whatever version is presently in
+# lfs-xml.
+#
+# It is recognized as a tag if it begins with x.y, where 'x' is one or more
+# digit(s), the '.' (dot) is mandatory, an 'y' is one or more digits. Anything
+# after y is allowed (for example 7.6-systemd or 8.1-rc1).
+#
+# It is recognized as a date if it is exactly 8 digits. Then it is assumed that
+# the format is YYYYMMDD.
+#
+# Note that there is no check that the tag or the date are valid. Svn errors
+# out if the tag is not valid, and if the date is impossible (that is MM>12
+# or DD>31), but it happily accepts YYYY=3018 (and updates to HEAD).
+#------
+# The tracking file is taken from Makefile in the same directory.
