You are encouraged to solve this task according to the task description, using any language you may know.
Fix Rosetta Code deprecated code tags, with these rules:
Change <%s> to <lang %s> Change </%s> to </lang> Change <code %s> to <lang %s> Change </code> to </lang>
Usage:
./convert.py < wikisource.txt > converted.txt
AutoHotkey
<lang AutoHotkey>; usage: > fixtags.ahk input.txt ouput.txt FileRead, text, %1% langs = ada,awk,autohotkey,etc slang = /lang slang := "<" . slang . "/>" Loop, Parse, langs, `, {
tag1 = <%A_LoopField%>
tag2 = </%A_LoopField%>
text := RegExReplace(text, tag1, "<lang " . A_LoopField . ">")
text := RegExReplace(text, tag2, slang)
text := RegExReplace(text, "(.*?)"
, "<lang $1>$2" . slang)

Here we implement the read_in function to read all the content from an input channel because there is no such function in the standard library, but we can use the extLib which provides the function Std.input_all (in its module Std).
