You'll also run into trouble using pull to grab an entire plain old darcs repository with a large initial commit. We can (and should) also optimize pull, but it's not going to ever be as efficient as a get is, for the case where you start with an empty repository. > There's also another problem: reading the git tree takes 220MB.

The output of linesPS actually does take a huge amount of space. -- David Roundy http://www.darcs.net
