+wxWidgets for DirectFB installation
+===================================
+
+IMPORTANT NOTE:
+
+  wxDFB is currently incomplete and some parts of the wxWidgets library
+  don't yet compile and must be disabled during configuration. In particular,
+  the coverage of wxDC API is limited.
+
+
+Dependencies
+------------
+
+wxDFB requires the DirectFB library (http://www.directfb.org), which must
+be installed before compiling wxDFB.
+
+
+Compiling
+---------
+
+Compilation is done in the standard Unix fashion, using configure and make.
+Please refer to e.g. wxGTK's install.txt for details if you are unfamiliar
+with configure.
+
+When configuring, use the --with-directfb option instead of e.g. --with-gtk
+to specify that the wxDFB port should be built. You'll also need to disable
+wxWidgets features that don't work in wxDFB yet:
+
+$ ./configure --with-directfb \
+              --with-themes=mono \
+              --disable-sockets \
+              --disable-accel \
+              --disable-display \
+              --disable-palette \
+              --disable-dataobj \
+              --disable-popupwin \
+              --disable-help \
+              --disable-combobox \
+              --disable-menus \
+              --disable-mdi \
+              --disable-mdidoc \
+              --disable-docview \
+              --disable-printarch \
+              --disable-calendar \
+              --disable-choice \
+              --disable-choicebook \
+              --disable-dirdlg \
+              --disable-filedlg \
+              --disable-fontdlg \
+              --disable-filepicker \
+              --disable-dirpicker \
+              --disable-fontpicker \
+              --disable-datepick \
+              --disable-hyperlink \
+              --disable-aui \
+              --disable-richtext \
+              --disable-fontmap \
+              --disable-xrc \
+              --disable-html
+$ make

+
+Configuring fonts
+-----------------
+
+DirectFB doesn't have native fonts configuration mechanism (such as
+fontconfig used by GTK+) and so wxDFB implements a simple configuration
+mechanism itself.
+
+No fonts are installed and configured by "make install", you have to manually
+configure fonts after you install the library.
+
+wxDFB looks the fonts up in directories specified in the WXDFB_FONTPATH
+environment variable (separated with :, similarly to the PATH variable).  If
+the variable is not set, $prefix/share/wx/fonts directory is used. All
+subdirectories of the directories on the path are scanned for FontsIndex
+files. These files are parsed and fonts defined in them are added to the fonts
+list.
+
+The FontsIndex file is standard wxFileConfig file text file. Each toplevel
+group specifies one font bundle, font's name is the name of group. Group's
+entries look like this:
+
+   [Font Name]
+   # font files (at least one of them must be present):
+   Regular=RegularFaceFile.ttf
+   Italic=ItalicFaceFile.ttf
+   Bold=BoldFaceFile.ttf
+   BoldItalic=BoldItalicFaceFile.ttf
+   # optional tag indicating this font is fixed-with (default is false):
+   IsFixed=1
+
+Additionally, there may be DefaultXXX entries at the toplevel for every family
+XXX and a Default entry that is shortcut for setting all families' default,
+their value is name of the default font:
+
+   # optional tags indicating the default font for given family:
+   DefaultDecorative=Font Name
+   DefaultRoman=Font Name
+   DefaultScript=Font Name
+   DefaultSwiss=Font Name
+   DefaultModern=Font Name
+   DefaultTeletype=Font Name
+   # indicate the font that is default for all families (optional):
+   Default=Font Name
+
+Any font formats supported by DirectFB (which typically includes formats
+supported by the FreeType library) can be used.
