This library contains some useful procs for dealing with text. There's not a lot of content here and I wouldn't normally post such a small library, but these procs are used by many other libraries. If each library that needs these procs defines them, including two of those libraries will result in a naming collisions.
replace("Hello, world!", "world", "BYOND")
var/list/l = split("a|b|c", "|")
merge(l, ", ")
