Which configure option in which PHP?

Hi, I prepare the configure options for the manual (as discussed the last days ;). On http://www.php.net/manual/en/install.configure.php you have entries like --with-curl[=DIR] PHP 3: Option not available in PHP 3 PHP 4: Include CURL support Just one question: How do I know, which option is available in PHP 3 and which in PHP 4? I plan to commit "short info" at first, so I think, there won't be any information about which option work in which PHP. But in the future, this will be implemented as well as links. The meaning of "short info" is, that there will only be the following for every option (not more _yet_). Every entry will look the same, no links, no more info. --with-ircg Include ircg support. Mark
