/* MARS needs to report many issues to scripts and to humans.
 * Many problems are not covered by POSIX and other errno definitions.
 *
 * IMPORTANT: keep the following namespaces unique within itself.
 * Keep MARS-specific namespace parts distinct from POSIX and others:
 *   (a) Integer (primary key)
 *   (b) C preprocessor macro names
 *   (c) Cleartext intended for humans.
 * Also, make any entry a 1:1:1 correspondence.
 *
 * While (a) and (b) are only defined here, the full
 * relationship (a) <=> (b) <=> (c) should reside in marsadm.
