+qBittorrent - A BitTorrent client in Qt4
+------------------------------------------
+
+This is the eComStation (OS/2) qBittorrent part of the readme. See also README for more general information.
+
+
+Building qBittorrent
+********************
+
+
+Requirements
+============
+
+- gcc based build env (recommended gcc v4.4.2 or greater)
+  
+- Qt4 for eCS (OS/2) dev package (see http://svn.netlabs.org/qt4 for more information)
+
+- libtorrent-rasterbar for eCS (OS/2) port (see http://svn.netlabs.org/ports for more information)
+
+- boost for eCS (OS/2) port (see http://svn.netlabs.org/ports for more information)
+
+
+How to build
+============
+
+First you need to create the conf.pri file in the same dir as this readme.os2 is.
+the conf.pri file has the following content:
+
+##### conf.pri content beginn #####
+PREFIX = .
+BINDIR = ./bin
+INCDIR = ./include
+LIBDIR = ./lib
+DATADIR = ./share
+
+CONFIG += staticlib
+INCLUDEPATH += x:/trees/libtorrent/trunk/include
+LIBS += -Lx:/trees/libtorrent/trunk/src/.libs \
+        -Lx:/trees/boost/trunk/stage/lib \
+        -Lx:/trees/openssl \
+	-Lx:/extras/lib
+##### conf.pri content end #####
+
+Of course all the above path references have to be adjusted to your build env.
+
+It should now be easy to build qBittorrent:
+
+Simply type:
+$ qmake
+
+Followed by:
+$ make
+
+If all works fine you should get a working qbittorrent executable.
+
+If you have any question regarding the eCS (OS/2) port of qBittorrent you can meet me (_diver) on IRC:
+#netlabs on irc.freenode.net
