Online Help
Webmin versions 0.63 and above now have support for context-sensitive help.
The hlink function outputs HTML for a link to a CGI program that
processes a given help page. Help pages are stored in the help
subdirectory under the module directory, and are named simple page.html.
So a call to hlink like
print &hlink("Enter username:", "name"),
"<input name=username size=20><p>\n";
would output a link to display the help page help/name.html.
