+ * ENVIRONMENT VARIABLES
+ * ---------------------
+ * Several options related to the interface with git can be configured
+ * via environment options.
+ *
+ * Repository references
+ * ~~~~~~~~~~~~~~~~~~~~~
+ * Commits that are referenced by tags and branch heads will be marked
+ * by the reference name surrounded by '[' and ']':
+ *
+ * 2006-03-26 19:42 Petr Baudis | [cogito-0.17.1] Cogito 0.17.1
+ *
+ * If you want to filter out certain directories under `.git/refs/`, say
+ * `tmp` you can do it by setting the following variable:
+ *
+ * $ TIG_LS_REMOTE="git ls-remote . | sed /\/tmp\//d" tig
+ *
+ * Or set the variable permanently in your environment.
+ *
+ * TIG_LS_REMOTE::
+ * Set command for retrieving all repository references. The command
+ * should output data in the same format as git-ls-remote(1).

+
+/**
+ * [[view-commands]]
+ * View commands
+ * ~~~~~~~~~~~~~
+ * It is possible to alter which commands are used for the different views.
+ * If for example you prefer commits in the main view to be sorted by date
+ * and only show 500 commits, use:
+ *
+ * $ TIG_MAIN_CMD="git log --date-order -n500 --pretty=raw %s" tig
+ *
+ * Or set the variable permanently in your environment.
+ *
+ * Notice, how `%s` is used to specify the commit reference. There can
+ * be a maximum of 5 `%s` ref specifications.
+ *
+ * TIG_DIFF_CMD::
+ * The command used for the diff view. By default, git show is used
+ * as a backend.
+ *
+ * TIG_LOG_CMD::
+ * The command used for the log view. If you prefer to have both
+ * author and committer shown in the log view be sure to pass
+ * `--pretty=fuller` to git log.
+ *
+ * TIG_MAIN_CMD::
+ * The command used for the main view. Note, you must always specify
+ * the option: `--pretty=raw` since the main view parser expects to
+ * read that format.

+/**
+ * The viewer
+ * ----------
+ *
+ * tig(1) presents various 'views' of a repository. Each view is based on output
+ * from an external command, most often 'git log', 'git diff', or 'git show'.
+ *
+ * The main view::
+ * Is the default view, and it shows a one line summary of each commit
+ * in the chosen list of revision. The summary includes commit date,
+ * author, and the first line of the log message. Additionally, any
+ * repository references, such as tags, will be shown.
+ *
+ * The log view::
+ * Presents a more rich view of the revision log showing the whole log
+ * message and the diffstat.
+ *
+ * The diff view::
+ * Shows either the diff of the current working tree, that is, what
+ * has changed since the last commit, or the commit diff complete
+ * with log message, diffstat and diff.
+ *
+ * The pager view::
+ * Is used for displaying both input from stdin and output from git
+ * commands entered in the internal prompt.
+ *
+ * The help view::
+ * Displays the information from the tig(1) man page. For the help view
+ * to work you need to have the tig(1) man page installed.
