+Completion requires a tags file.  You should use Exuberant ctags, because it
+adds extra information that is needed for completion.  You can find it here:
+http://ctags.sourceforge.net/
+For version 5.5.4 you need to add a patch that adds the "typename:" field:
+ftp://ftp.vim.org/pub/vim/unstable/patches/ctags-5.5.4.patch
+
+If you want to complete system functions you can do something like this.  Use
+ctags to generate a tags file for all the system header files: >
+	% ctags -R -f ~/.vim/systags /usr/include /usr/local/include
+In your vimrc file add this tags file to the 'tags' option: >
+	set tags+=~/.vim/systags
+
+When using CTRL-X CTRL-O after a name without any "." or "->" it is completed
+from the tags file directly.  This works for any identifier, also function
+names.  If you want to complete a local variable name, which does not appear
+in the tags file, use CTRL-P instead.
+
+When using CTRL-X CTRL-O after something that has "." or "->" Vim will attempt
+to recognize the type of the variable and figure out what members it has.
+This means only members valid for the variable will be listed.
+
+Vim doesn't include a C compiler, only the most obviously formatted
+declarations are recognized.  Preprocessor stuff may cause confusion.
+When the same structure name appears in multiple places all possible members
+are included.
