$regsub([name], text, re, subtext, %var)
Performs a regular expression match, like $regex(), and then performs a substitution using subtext.

Example:
alias testing {
var %num_of_matches = $regsub(a dog was eating milk,/dog/g,cat,%new_content)
;%num_of_matches will have a value of 1, since 'dog' was matched once
;%new_content will be 'a cat was eating milk'
