String.abbrev (info [, length]) returns 1 if info is a prefix of string "abcdef".abbrev (" xyz ") returns 0.

abbrev (info [，length])如果info是string的前缀，返回1 “ abcdef ” . abbrev (“ xy z ”)返回0。

The "abbrev" field in the hash entry is used to define command-line switches, so later I can define an -artist switch that can be abbreviated to -i based on the % freedb_searches information.

在该散列条目中的“abbrev”字段被用来定义命令行开关，这样，随后我可以基于% freedb_searches信息定义一个- artist开关，它可以被简写为- i。
