In
Perl, the qw() operator takes a series of
strings seperated by
white space and returns them so they may be treated as if they were in quotes. Example:
qw(one two three)
is the same as
("one","two","three").
Note
Do not use commas between the arguements(e.g. qw(one,two,three)). It doesn't work properly.
