# Mechanism to generate static HTML redirect pages in the output
|
|

|
|

|
# Uses redirect_template.html and the list of pages given in

# the file conf.html_redirect_pages

|
|
|
# Redirections can be internal or absolute (i.e., external).
|
|
|
|
# - Internal redirects are supplied without quotation marks and must be relative to the document root
|
|
|
|
# - External redirects are wrapped in doulbe quotation marks and are used verbatim
