+dnl ATF_CHECK_SH([version-spec])
+dnl
+dnl Checks if atf-sh is present.  If version-spec is provided, ensures that
+dnl the installed version of atf-sh matches the required version.  This
+dnl argument must be something like '>= 0.14' and accepts any version
+dnl specification supported by pkg-config.
+dnl
+dnl Defines and substitutes ATF_SH with the full path to the atf-sh interpreter.
