annotate mercurial/changelog.py @ 1913:74cf2b2f43d4

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
fix some things people wanted to be cleaner. rename --map-file to --style. no more -t alias for --template. update docs. rename template entry in map files to changelog. if --verbose, use changelog_verbose if there, else changelog.
