perl-Text-ParseWords - parse text into an array of tokens or array of arrays

Description:

The &nested_quotewords() and &quotewords() functions accept a delimiter
(which can be a regular expression) and a list of lines and then breaks
those lines up into a list of words ignoring delimiters that appear
inside quotes. &quotewords() returns all of the tokens in a single long
list, while &nested_quotewords() returns a list of token lists corresponding
to the elements of @lines. &parse_line() does tokenizing on a single string.
The &*quotewords() functions simply call &parse_line(), so if you're only
splitting one line you can call &parse_line() directly and save a function call.
The $keep argument is a boolean flag. If true, then the tokens are split
on the specified delimiter, but all other characters (quotes, backslashes,
etc.) are kept in the tokens. If $keep is false then the &*quotewords()
functions remove all quotes and backslashes that are not themselves
backslash-escaped or inside of single quotes (i.e., &quotewords() tries to
interpret these characters just like the Bourne shell). NB: these semantics
are significantly different from the original version of this module shipped
with Perl 5.000 through 5.004. As an additional feature, $keep may be the
keyword "delimiters" which causes the functions to preserve the delimiters
in each string as tokens in the token lists, in addition to preserving quote
and backslash characters.
&shellwords() is written as a special case of &quotewords(), and it does
token parsing with whitespace as a delimiter-- similar to most Unix shells.
