+# set, the build system will abort if our dependent libraries and their
+# header files are not found on the target system.  This will mean for

+# default build to complete.  The configure system will check for these
+# headers, and the error message will indicate the option (such as
+# --without-acl-support) that can be specified to skip this requirement.

+# This will assist users and in particular distributors in building fully
