This directory contains marker directories.

These are used to control redirects from dist/GHOST using the httpd config:

    RewriteCond "%{REQUEST_URI}" "^/dist/([-a-zA-Z0-9]+)"
    RewriteCond "/var/www/attic.apache.org/flags/%1.apache.org/" -d
    RewriteRule ".*" "http://attic.apache.org/projects/%1.html" [R=307,L]

This assumes that the dist/GHOST name is the same as the generated HTML file stem.
This is currently the case for all the TLPs.

Some of the directories contain 'banners' files
These are used to control which websites have banners added.
The chttpd onfig uses a condition such as:

    <If "-f '/var/www/attic.apache.org/flags/%{HTTP_HOST}/banners'">

This assumes that dist/GHOST has a website at GHOST.apache.org
This is true at present.

Also that subprojects will never need banners independently of the parent project
This is not true for some historic Attic entries, e.g. OJB
