+bitmessage for Debian
+--------------------
+
+In order to build the .deb yourself, you'll first have to install the stuff that's neccessary to compile .debs:
+
+
+apt-get install python-minimal python-setuptools python-all \
+    python openssl libssl-dev dh-apparmor debhelper dh-python \
+    python-msgpack python-qt4 git
+
+
+Next make some build directory and clone the newest git repository:
+
+And if I haven't forgotten anything, you can build the .deb package now:
+
+
+dpkg-buildpackage -us -uc
+
+
+I've tried this with Debian Buster, but I'd expect it to work on most if not all recent debian-based distributions. Maybe with some minor changes.

+Description: BitMessage Anonymous Communication Client
+ .
+ Bitmessage is a P2P communication protocol used to send encrypted messages to another person or to many subscribers. It is decentralized and trustless, meaning that you need-not inherently trust any entities like root certificate authorities. It uses strong authentication, which means that the sender of a message cannot be spoofed. BM aims to hide metadata from passive eavesdroppers like those ongoing warrantless wiretapping programs. Hence the sender and receiver of Bitmessages stay anonymous.

-Basic infrastructure for asynchronous socket service clients and servers.
-
-There are only two ways to have a program on a single processor do "more
-than one thing at a time".  Multi-threaded programming is the simplest and
-most popular way to do it, but there is another very different technique,
-that lets you have nearly all the advantages of multi-threading, without
-actually using multiple threads. it's really only practical if your program
-is largely I/O bound. If your program is CPU bound, then pre-emptive
-scheduled threads are probably what you really need. Network servers are
-rarely CPU-bound, however.
-
-If your operating system supports the select() system call in its I/O
-library (and nearly all do), then you can use it to juggle multiple
-communication channels at once; doing other work while your I/O is taking
-place in the "background."  Although this strategy can seem strange and
-complex, especially at first, it is in many ways easier to understand and
-control than multi-threaded programming. The module documented here solves
-many of the difficult problems for you, making the task of building
-sophisticated high-performance network servers and clients a snap.
