moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).
sort_map: Remove duplicates resulting from multiple outputs for the same input. mappings/Makefile: $(mkSelfMap): Removed uniq now that sort_map does this.
Added sort_map to sort a map spreadsheet in the standard order
