20	*
21	* VBoxService is a root daemon for implementing guest additions features.
22	*
23	* It is structured as one binary that contains many sub-services. The reason
24	* for this is partially historical and partially practical. The practical
25	* reason is that the VBoxService binary is typically statically linked, at
26	* least with IPRT and the guest library, so we save quite a lot of space having
27	* on single binary instead individual binaries for each sub-service and their
28	* helpers (currently up to 9 subservices and 8 helpers). The historical is
29	* simply that it started its life on OS/2 dreaming of conquring Windows next,
30	* so it kind of felt natural to have it all in one binary.
31	*
32	* Even if it's structured as a single binary, it is possible, by using command
33	* line options, to start each subservice as an individual process.
34	*
35	* Subservices:
36	* - @subpage pg_vgsvc_timesync "Time Synchronization"
37	* - @subpage pg_vgsvc_vminfo "VM Information"
38	* - @subpage pg_vgsvc_vmstats "VM Statistics"
39	* - @subpage pg_vgsvc_gstctrl "Guest Control"
40	* - @subpage pg_vgsvc_pagesharing "Page Sharing"
41	* - @subpage pg_vgsvc_memballoon "Memory Balooning"
42	* - @subpage pg_vgsvc_cpuhotplug "CPU Hot-Plugging"
43	* - @subpage pg_vgsvc_automount "Shared Folder Automounting"
44	* - @subpage pg_vgsvc_clipboard "Clipboard (OS/2 only)"
45	*
46	* Now, since the service predates a lot of stuff, including RTGetOpt, we're
47	* currently doing our own version of argument parsing here, which is kind of
48	* stupid. That will hopefully be cleaned up eventually.
