+===========
+
+NAME
+----
+git-show - Show various types of objects
+
+
+SYNOPSIS
+--------
+[verse]
+'git show' [<options>] [<object>...]
+
+DESCRIPTION
+-----------
+Shows one or more objects (blobs, trees, tags and commits).
+
+For commits it shows the log message and textual diff. It also
+presents the merge commit in a special format as produced by
+'git diff-tree --cc'.
+
+For tags, it shows the tag message and the referenced objects.
+
+For trees, it shows the names (equivalent to 'git ls-tree'
+with --name-only).
+
+For plain blobs, it shows the plain contents.
+
+Some options that 'git log' command understands can be used to
+control how the changes the commit introduces are shown.
+
+This manual page describes only the most frequently used options.
+
+
+OPTIONS
+-------
+<object>...::
+	The names of objects to show (defaults to 'HEAD').
+	For a more complete list of ways to spell object names, see
+	"SPECIFYING REVISIONS" section in linkgit:gitrevisions[7].
