Subject: Make downloaded files accessible via the HTTP server.
X-Git-Url: https://git.mxchange.org/?p=quix0rs-apt-p2p.git;a=commitdiff_plain;h=3348b1340e4c881d930071e85d0ef986c71c93cf

Make downloaded files accessible via the HTTP server.

MirrorManager calls back to the main code, which adds an
appropriate ~ (tilde) directory to the web server.
