-\title Issues to be aware of when porting Qt/Embedded
-
-Qt/Embedded is designed to be reasonably platform-independent. The
-only publically available version is a Linux implementation. The
-following dependencies will need to be addressed if you intend to port
-to another operating system (files that you need to modify are listed
-at the end of each section):
-
-
-\list 
-
-\i <b>System V IPC</b> (shared memory and semaphores) is used to share
-window regions between client and server. You will need to provide
-something similar unless you want a single-application setup (i.e.
-running only one program, which is the server). System V semaphores
-are also used for synchronising access to the framebuffer.
-
-Modify \c qwindowsystem_qws.cpp, \c qwsregionmanager_qws.cpp, \c
-qapplication_qws.cpp, and \c qlock_qws.cpp.
-
-\i <b>Unix-domain sockets</b> are used to communicate things like
-keyboard events, requests to raise windows and QCOP messages between
-applications. Again, you will need to provide something similar unless
-you want a single-application setup. It should be possible to
-implement something like this using message queues or similar
-mechanisms; with the exception of QCOP messages (which are generated
-by client applications and not Qt/Embedded) individual messages should
-be no more than a few bytes in length. 
-
-Modify \c qwssocket_qws.cpp.
-
-\i <b>The Linux framebuffer device</b> is used to map in the drawing
-area. You will need to replace it (by creating a new class of QScreen)
-with something else giving a byte pointer to a memory-mapped
-framebuffer, plus information about width, height and bit depth (which
-most likely you can simply hard-code). If your framebuffer is not
-memory-mapped or is in an unsupported format or depth you will need to
-modify QGfxRaster as well. 
-
-Modify \c qgfxlinuxfb_qws.cpp.
-
-\i <b>The accelerated drivers</b> currently use the Linux QScreen and use
-\c /proc/bus/pci to map in PCI config space. However, these are only
-example drivers; you will probably need to write your own driver in
-any case, and you will need to provide your own way to map in control
-registers. 
-
-Modify \c qgfxmach64_qws.cpp, \c qgfxvoodoo_qws.cpp and \c
-qgfxmatrox_qws.cpp.
-
-\i <b>Sound</b> uses a Linux \c /dev/dsp style device. If you want to use
-the Qt/Embedded sound server you'll need to reimplement it.
-
-Modify \c qsoundqss_qws.cpp.
-
-\i <b>select()</b> is used to implement QSocketDevices and listen for
-events to/from the Qt/Embedded server application.
-
-Modify \c qapplication_qws.cpp.
-
-\endlist
-
-Qt/Embedded makes use of the standard C library and some Posix functions.
-Mostly the latter are concentrated in platform dependent code anyway
-(e.g. mmap() to map in the Linux framebuffer).
