Looking into bundle files
[:Bundle] files may contain either all or some of the [:ChangeSet:changesets] in a [:Repository:repository]. To view a partial bundle, you must have a repository containing the bundle's base changesets. Then you can overlay the bundle on top of the repo like so:
$ cd repo $ hg in bundle.hg # view the changesets added by the bundle $ hg -R bundle.hg log # view the log of repo+bundle $ hg -R bundle.hg diff -r tip # compare the working dir to the bundle's tip $ hg -R bundle.hg cat -r tip foo.txt # extract a particular file
