30  * This header file should not exist.
31  *
32  * Whether it be due to laziness, machismo, or just plain cluelessness, most
33  * of the symbols over in psm/stand are not properly prototyped anywhere.
34  *
35  * To workaround this, developers have adopted the horrendous practice of
36  * "externing" the symbols they need, leading to dozens of declarations of
37  * the same symbol which have to be kept in sync.  Unfortunately, no similar
38  * workaround exists for lint's pass2, which requires definitions for all
39  * symbols in order to properly perform cross-checks.
40  *
41  * Thus, this header file was created to address the problems:
42  *
43  *	- The "extern" problem.  All files beneath stand/lib should #include
44  *	  this file rather than "extern" the symbol. Additionally, existing
45  *	  externs should be removed as convenient.
46  *
47  *	  Of course, eventually some brave soul needs to venture over to the
48  *	  slums of psm/stand and add all the proper header files, at which
49  *	  point this file can be disposed of.
50  *
51  * Note that the set of symbols shared between stand/lib and psm/stand is
52  * itself a moving target.  As such, this file should be updated as needed
53  * so that it always contains the *minimum* set of shared symbols needed to
54  * avoid externs and placate lint.
