/*
 * This header file should not exist.
 *
 * Whether it be due to laziness, machismo, or just plain cluelessness, most
 * of the symbols over in psm/stand are not properly prototyped anywhere.
 *
 * To workaround this, developers have adopted the horrendous practice of
 * "externing" the symbols they need, leading to dozens of declarations of
 * the same symbol which have to be kept in sync.  Unfortunately, no similar
 * workaround exists for lint's pass2, which requires definitions for all
 * symbols in order to properly perform cross-checks.
 *
 * Thus, this header file was created to address the problems:
 *
 *	- The "extern" problem.  All files beneath stand/lib should #include
 *	  this file rather than "extern" the symbol. Additionally, existing
 *	  externs should be removed as convenient.
 *
 *	  Of course, eventually some brave soul needs to venture over to the
 *	  slums of psm/stand and add all the proper header files, at which
 *	  point this file can be disposed of.
 *
 * Note that the set of symbols shared between stand/lib and psm/stand is
 * itself a moving target.  As such, this file should be updated as needed
 * so that it always contains the *minimum* set of shared symbols needed to
 * avoid externs and placate lint.
