  use external program to diff repository (or selected files)
  
      Show differences between revisions for the specified files, using an
      external program. The default program used is diff, with default options
      "-Npru".
  
      To select a different program, use the -p/--program option. The program
      will be passed the names of two directories to compare. To pass additional
      options to the program, use -o/--option. These will be passed before the
      names of the directories to compare.
  
      When two revision arguments are given, then changes are shown between
      those revisions. If only one revision is specified then that revision is
      compared to the working directory, and, when no revisions are specified,
      the working directory files are compared to its parent.
  
  use "hg help -e extdiff" to show help for the extdiff extension

   -p --program CMD         comparison program to run
   -o --option OPT [+]      pass option to comparison program

   -I --include PATTERN [+] include names matching the given patterns

  $ hg help --extension extdiff
  extdiff extension - command to allow external programs to compare revisions
  
  The extdiff Mercurial extension allows you to use external programs to compare
  revisions, or revision with working directory. The external diff programs are
  called with a configurable set of options and two non-option arguments: paths
  to directories containing snapshots of files to compare.
  
  The extdiff extension also allows you to configure new diff commands, so you
  do not need to type "hg extdiff -p kdiff3" always.
  
    [extdiff]
    # add new command that runs GNU diff(1) in 'context diff' mode
    cdiff = gdiff -Nprc5
    ## or the old way:
    #cmd.cdiff = gdiff
    #opts.cdiff = -Nprc5
  
    # add new command called vdiff, runs kdiff3
    vdiff = kdiff3
  
    # add new command called meld, runs meld (no need to name twice)
    meld =
  
    # add new command called vimdiff, runs gvimdiff with DirDiff plugin
    # (see http://www.vim.org/scripts/script.php?script_id=102) Non
    # English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in
    # your .vimrc
    vimdiff = gvim -f '+next' '+execute "DirDiff" argv(0) argv(1)'
  
  Tool arguments can include variables that are expanded at runtime:
  
    $parent1, $plabel1 - filename, descriptive label of first parent
    $child,   $clabel  - filename, descriptive label of child revision
    $parent2, $plabel2 - filename, descriptive label of second parent
    $root              - repository root
    $parent is an alias for $parent1.
  
  The extdiff extension will look in your [diff-tools] and [merge-tools]
  sections for diff tool arguments, when none are specified in [extdiff].
  
    [extdiff]
    kdiff3 =
  
    [diff-tools]
    kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child
  
  You can use -I/-X and list of file or directory names like normal "hg diff"
  command. The extdiff extension makes snapshots of only needed files, so
  running the external diff program will actually be pretty fast (at least
  faster than having to compare the entire tree).
  
  list of commands:
  
   extdiff   use external program to diff repository (or selected files)
  
  use "hg -v help extdiff" to show builtin aliases and global options

  $ echo 'extdiff = !' >> $HGRCPATH

  $ hg help multirevs
  Specifying Multiple Revisions
  
      When Mercurial accepts more than one revision, they may be specified
      individually, or provided as a topologically continuous range, separated
      by the ":" character.
  
      The syntax of range notation is [BEGIN]:[END], where BEGIN and END are
      revision identifiers. Both BEGIN and END are optional. If BEGIN is not
      specified, it defaults to revision number 0. If END is not specified, it
      defaults to the tip. The range ":" thus means "all revisions".
  
      If BEGIN is greater than END, revisions are treated in reverse order.
  
      A range acts as a closed interval. This means that a range of 3:5 gives 3,
      4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
  
  use "hg help -c multirevs" to see help for the multirevs command

  $ hg help -c multirevs
  hg multirevs ARG
