to place them.

Create a new Git command called `repo`. `git repo` will be the main
command for obtaining the information about a repository (such as
metadata and metrics), returning them in a machine readable format
following the syntax "field<LF>value<NUL>".

Also declare a subcommand for `repo` called `info`. `git repo info`
will bring the functionality of retrieving repository-related
information currently returned by `rev-parse`.

Also add entries for this new command in:

- the build files (Makefile, meson.build, Documentation/meson.build)
- builtin.h
- git.c
- .gitignore
- command-list.txt
- Documentation

+NAME
+----
+git-repo - Retrieve information about a repository
+
+SYNOPSIS
+--------
+[synopsis]
+git repo info [<key>...]
+
+DESCRIPTION
+-----------
+Retrieve information about the current repository in a machine-readable format.
+
+`git repo` will be the primary tool to query repository-specific information,
+such as metadata that currently can also be done by calling `git rev-parse` (see
+linkgit:git-rev-parse[1]). `git repo` doesn't query information unrelated to the
+current repository or that is already retrieved by a specialized command, for
+example, `git config` (see linkgit:git-config[1]) or `git var` (see
+linkgit:git-var[1]).
+
+This command returns the retrieved data following a null-terminated format with
+this syntax:
++
+----------------
+key1<LF>value1<NUL>
+key2<LF>value2<NUL>
+...
+----------------
