+git-sh-i18n(1)
+==============
+
+NAME
+----
+git-sh-i18n - Git's i18n setup code for shell scripts
+
+SYNOPSIS
+--------
+'. "$(git --exec-path)/git-sh-i18n"'
+
+DESCRIPTION
+-----------
+
+This is not a command the end user would want to run.  Ever.
+This documentation is meant for people who are studying the
+Porcelain-ish scripts and/or are writing new ones.
+
+The 'git sh-i18n scriptlet is designed to be sourced (using
+`.`) by Git's porcelain programs implemented in shell
+script. It provides wrappers for the GNU `gettext` and
+`eval_gettext` functions accessible through the `gettext.sh`
+script, and provides pass-through fallbacks on systems
+without GNU gettext.
+
+FUNCTIONS
+---------
+
+gettext::
+	On GNU systems this will be the `gettext` function from
+	`gettext.sh`, on Solaris it`ll be the `gettext(1)`
+	command.
+
+	If neither of those implementations are available a
+	dummy fall-through function is provided.
+    
+eval_gettext::
+	On GNU systems this will be the `eval_gettext` function
+	from `gettext.sh`, on Solaris we provide an
+	`eval_gettext` using the
+	linkgit:git-sh-i18n--envsubst[1] helper.
+
+	If neither of those implementations are available a
+	dummy fall-through function is provided.
