/* THE B7 OPTION */
/* ------------- */
/* When FunnelWeb was first ported to different machines and the regression */
/* testing was activated, a most irritating occurance was the failure of the */
/* results of tests on different machines to compare, because of minor */
/* differences in implementation. For example, error messages that contained */
/* file names would differ because the directory name on different machines */
/* was different. Another example was error messages that quoted */
/* implementation limits. This problem was solved by creating the B7 option */
/* which instructs FunnelWeb to suppress all output that is */
/* non-deterministic, machine specific, or which in any other way would cause */
/* an unncessary failure of the test suite. */
/* The following symbol provides a simple replacement for filenames in error */
/* messages. */

/******************************************************************************/
/* The following structure stores all the information that can be */
/* communicated in one or more command lines. An important aspect of the */
/* structure is that it is totally self contained; it does not contain any */
/* pointers to outside structures such as command lines. */
/* The rather strange field names are explained as follows: */
/* 1) Local names must be distinct to 8 characters (for portability). */
/* 2) All structure field names should be unique (for portability). */
/* Some of the older compilers use a single field structure name space. */
/* 3) The op_ is used as a prefix for entities in this whole package. */
/* 4) The next letter is the option letter itself. It is not intended that */
/* the command line option names be tightly bound to the internal */
/* identifier names -- the command line names are just convenient. */
/* 5) The next letter gives the type: [B]oolean, [S]tring, [I]nteger. */
