30  * Overview of poolcfg(1)
31  *
32  * poolcfg(1) implements a small grammar for manipulating pools configurations.
33  * yacc(1) is used to generate the parser and poolcfg.l contains a simple lexer
34  * (generted by lex(1)) to perform lexical processsing of the input.
35  *
36  * Refer to the poolcfg(1) manpage for more details of the grammar.
37  *
38  * The parser is designed so that all operations implement the same interface.
39  * This allows the parser to simply build up the command (using the cmd
40  * variable) by storing arguments and a pointer to the desired function in the
41  * cmd. The command is executed when the commands production is matched.
42  *
43  * Properties and associations are stored in simple linked lists and processed
44  * in the order submitted by the user.
