29 * zonecfg is a lex/yacc based command interpreter used to manage zone
30 * configurations. The lexer (see zonecfg_lex.l) builds up tokens, which
31 * the grammar (see zonecfg_grammar.y) builds up into commands, some of
32 * which takes resources and/or properties as arguments. See the block
33 * comments near the end of zonecfg_grammar.y for how the data structures
34 * which keep track of these resources and properties are built up.
35 *
36 * The resource/property data structures are inserted into a command
37 * structure (see zonecfg.h), which also keeps track of command names,
38 * miscellaneous arguments, and function handlers. The grammar selects
39 * the appropriate function handler, each of which takes a pointer to a
40 * command structure as its sole argument, and invokes it. The grammar
41 * itself is "entered" (a la the Matrix) by yyparse(), which is called
42 * from read_input(), our main driving function. That in turn is called
43 * by one of do_interactive(), cmd_file() or one_command_at_a_time(), each
44 * of which is called from main() depending on how the program was invoked.
45 *
46 * The rest of this module consists of the various function handlers and
47 * their helper functions. Some of these functions, particularly the
48 * X_to_str() functions, which maps command, resource and property numbers
49 * to strings, are used quite liberally, as doing so results in a better
50 * program w/rt I18N, reducing the need for translation notes.
