Doesnt work under 1.16
When I copied and pasted, I got the error Parse error: syntax error, unexpected ':' in /path/to/mw/extensions/Code/Code.php on line 57. It turned out that the cause was a newline that got inserted into the earlier comment
#$source = "file_get_contents disabled! Contact Mike Sullivan at x3126 with questions.";
I replaced the name and extension with an email address, removed the newline, and it works fine now.
in Code directory, after syntaxhightlight extension install, create sim-link of geshi lib in Code extension directory
ln -s ../SyntaxHighlight_GeSHi/geshi/ .
and all work
