Help for uncommit

  $ hg help uncommit
  hg uncommit [OPTION]... [FILE]...
  
  uncommit part or all of a local changeset
  
      This command undoes the effect of a local commit, returning the affected
      files to their uncommitted state. This means that files modified or
      deleted in the changeset will be left unchanged, and so will remain
      modified in the working directory.
  
      If no files are specified, the commit will be pruned, unless --keep is
      given.
  
  (use 'hg help -e uncommit' to show help for the uncommit extension)
  
  options ([+] can be repeated):
  
      --keep                     allow an empty commit after uncommitting
      --allow-dirty-working-copy allow uncommit with outstanding changes
   -n --note TEXT                store a note on uncommit
   -I --include PATTERN [+]      include names matching the given patterns
   -X --exclude PATTERN [+]      exclude names matching the given patterns
   -m --message TEXT             use text as commit message
   -l --logfile FILE             read commit message from file
   -d --date DATE                record the specified date as commit date
   -u --user USER                record the specified user as committer
   -D --currentdate              record the current date as commit date
   -U --currentuser              record the current user as committer
  
  (some details hidden, use --verbose to show complete help)
