+The @file{system-gdbinit} directory, located inside the data-directory
+(as specified by @option{--with-gdb-datadir} at configure time) contains
+a number of scripts which can be used as system-wide init files.  To
+automatically source those scripts at startup, @value{GDBN} should be
+configured with @option{--with-system-gdbinit}.  Otherwise, any user
+should be able to source them by hand as needed.

+The following scripts are currently available:

+This script is useful when debugging a program on an ELinOS target.
+It takes advantage of the environment variables defined in a standard
+ELinOS environment in order to determine the location of the system
+shared libraries, and then sets the @samp{solib-absolute-prefix}
