-     only show at most two initials instead of the usual three  
+   * `--two-initials`
+     only show at most two initials instead of the usual three

-   * `--author-date`  
-     force use of author dates and times  
+   * `--author-date`
+     force use of author dates and times
      The default is to use committer dates and times unless
      `--author-date-order` is in effect.  This option forces author
      dates and times to always be used and overrides `--committer-date`.
 
-   * `--committer-date`  
-     force use of committer dates and times  
+   * `--committer-date`
+     force use of committer dates and times
      The default is to use committer dates and times if `--date-order` or
      `--topo-order` is in effect or `--author-date-order` is NOT in effect.
      This option forces committer dates and times to always be used and
      overrides a previous `--author-date` option.

-     show author and commiter initials separated by a `/`  
+   * `--initials=author,committer`

 config value and they will be treated as though they appeared at

+Making it run faster
+--------------------
+
+The things that take git-log-compact the longest are reading configuration.
+Therefore, for maximum speed, specify all the configuration in
+`GIT_LOG_COMPACT_OPTIONS`.  For example (in `bash`):
+
+    export GIT_LOG_COMPACT_OPTIONS="--decorate --color=always --pager=less --default-colors"
