mq extension - patch management and development
|
|
|
|
|
|
This extension lets you work with a stack of patches in a Mercurial
|
|
|
repository. It manages two stacks of patches - all known patches, and
|
|
|
applied patches (subset of known patches).
|
|
|
|
|
|
Known patches are represented as patch files in the .hg/patches
|
|
|
directory. Applied patches are both patch files and changesets.
|
|
|
|
|
|
