+# NOTE: This conversion has been made and merge.
+# This "one-shot" script is not required anymore,
+# it is only kept here for historical interest.

+# This script imports 3301 revisions of CSS 2,
+# dated from 1997-07-21 to 2014-01-17,
+# from a zip archive of W3C's CVS repository into a Mercurial bundle file.
+#
+# This bundle can be imported into a clone of CSSWG's repository
+# (https://dvcs.w3.org/hg/csswg/) to add a 'css2' subdirectory
+# with all its change history:
+#
+#     hg unbundle path/to/css2.hg-bundle
+#     hg merge
+#     hg commit -m 'Import CSS 2 from CVS, with change history'
+
+# This script requires cvs2svn and hg convert
+#     http://cvs2svn.tigris.org/
+#     http://mercurial.selenic.com/wiki/ConvertExtension
+#
+# It expects to be in the same directory as a 'css2.zip' file
+# containing the 'css2-src' directory of W3C's internal CVS repository,
+# which itself consists of a bunch of '*,v' files.
+#
+# It will go through a multiple-step conversion, creating temporary files
+# in the 'tmp' subdirectory, to finally produce a ~10 MB 'css2.hg-bundle' file.

+# We may end up with incorrect earlier versions of bin/mkidx
+# but at least cvs2svn doesn't abort in the middle of the conversion
