/*
 * 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.
