/*
* zonecfg is a lex/yacc based command interpreter used to manage zone
* configurations. The lexer (see zonecfg_lex.l) builds up tokens, which
* the grammar (see zonecfg_grammar.y) builds up into commands, some of
* which takes resources and/or properties as arguments. See the block
* comments near the end of zonecfg_grammar.y for how the data structures
* which keep track of these resources and properties are built up.
*
* The resource/property data structures are inserted into a command
* structure (see zonecfg.h), which also keeps track of command names,
* miscellaneous arguments, and function handlers. The grammar selects
* the appropriate function handler, each of which takes a pointer to a
* command structure as its sole argument, and invokes it. The grammar
* itself is "entered" (a la the Matrix) by yyparse(), which is called
* from read_input(), our main driving function. That in turn is called
* by one of do_interactive(), cmd_file() or one_command_at_a_time(), each
* of which is called from main() depending on how the program was invoked.
*
* The rest of this module consists of the various function handlers and
* their helper functions. Some of these functions, particularly the
* X_to_str() functions, which maps command, resource and property numbers
* to strings, are used quite liberally, as doing so results in a better
* program w/rt I18N, reducing the need for translation notes.
