Release Name: 0.4.2

Notes:
sub is a wrapper for svn that adds faster/safer updates, easy trunk checkout, etc.


Changes:
== 0.4.0\n\n* "sub ext" command to deal with svn:externals property (see "sub help")
* "sub ignore" command to either print or add to a directory's svn:ignore
  property
* If you replace an external with a "real" directory, then use "sub up" in
  another workspace, it will now do the right thing and remove the external
  before updating the directory. (This solves what is, IMHO, a bug in svn --
  it gets confused and attempts to grab its own lock and aborts.)
