-# This is the cmake-based build system for Quassel IRC.
-# You may pass various options to cmake:
-# -DWANT_(CORE|QTCLIENT|MONO)=(ON|OFF)
-#                     : select binaries to build
-# -DWITH_OPENSSL=OFF  : Disable OpenSSL support
-# -DWITH_DBUS=OFF     : Disable D-Bus support
-# -DQT=/path/to/qt    : Choose a Qt4 installation to use instead of the system Qt4
-# -DSTATIC=ON         : Enable static building of Quassel. Use with care.
-# -DSPUTDEV=ON        : Do not use.
-# -DDEPLOY=ON         : Mac OS X only. Use only fore redistribution Quassel Packages!!
+# Main CMake file for building Quassel IRC
 #
-# NOTE: You need to remove CMakeCache.txt if you plan to change any of these values!
+# See INSTALL for possible CMake options (or read the code, Luke)
