Final answer:
The parser General command -V or -VERBOSE is used to enable verbose mode, offering additional detailed information useful for debugging or understanding the process of parsing more clearly.
Step-by-step explanation:
The parser General command -V or -VERBOSE is used to enable verbose mode during parsing. When this command is issued, the parser provides more detailed information about what it's doing, which can be helpful for debugging or understanding the parsing process in greater detail. Typically, without verbose mode, a parser might simply output the result or errors. However, with verbose mode enabled, it may offer contextual information, such as which rules or tokens are being processed at each step of the parsing.
