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.
