23 | * [verse] | |
03a93dbb JF |
24 | * tig [options] |
25 | * tig [options] [--] [git log options] | |

31 | * DESCRIPTION | |
32 | * ----------- | |
6706b2ba JF |
33 | * Browse changes in a git repository. Additionally, tig(1) can also act |
34 | * as a pager for output of various git commands. | |
35 | * | |
57bdf034 | 36 | * When browsing repositories, tig(1) uses the underlying git commands |
468876c9 JF |
37 | * to present the user with various views, such as summarized commit log |
38 | * and showing the commit with the log message, diffstat, and the diff. | |
6706b2ba | 39 | * |
468876c9 JF |
40 | * Using tig(1) as a pager, it will display input from stdin and try |
41 | * to colorize it. | |
