Zbigniew Jędrzejewski-Szmek 3a54a15760 man: use same header for all files
The "include" files had type "book" for some raeason. I don't think this
is meaningful. Let's just use the same everywhere.

$ perl -i -0pe 's^..DOCTYPE (book|refentry) PUBLIC "-//OASIS//DTD DocBook XML V4.[25]//EN"\s+"http^<!DOCTYPE refentry PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"\n  "http^gms' man/*.xml

<title>Description</title>
<para><command>systemd-inhibit</command> may be used to execute a
program with a shutdown, sleep, or idle inhibitor lock taken. The
lock will be acquired before the specified command line is
executed and released afterwards.</para>
<para>Inhibitor locks may be used to block or delay system sleep
and shutdown requests from the user, as well as automatic idle
handling of the OS. This is useful to avoid system suspends while
an optical disc is being recorded, or similar operations that
should not be interrupted.</para>

Lock Developer Documentation</ulink>.</para>

<title>Options</title>
<para>The following options are understood:</para>
<variablelist>
<varlistentry>
<term><option>--what=</option></term>
<listitem><para>Takes a colon-separated list of one or more
operations to inhibit:
<literal>shutdown</literal>,
<literal>sleep</literal>,
<literal>idle</literal>,
<literal>handle-power-key</literal>,
<literal>handle-suspend-key</literal>,
<literal>handle-hibernate-key</literal>,
<literal>handle-lid-switch</literal>,
for inhibiting reboot/power-off/halt/kexec,
suspending/hibernating, the automatic idle detection, or the
low-level handling of the power/sleep key and the lid switch,
respectively. If omitted, defaults to
<literal>idle:sleep:shutdown</literal>.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>--who=</option></term>
<listitem><para>Takes a short, human-readable descriptive
string for the program taking the lock. If not passed,
defaults to the command line string.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>--why=</option></term>
<listitem><para>Takes a short, human-readable descriptive
string for the reason for taking the lock. Defaults to
"Unknown reason".</para></listitem>
</varlistentry>
<varlistentry>
<term><option>--mode=</option></term>
<listitem><para>Takes either <literal>block</literal> or
<literal>delay</literal> and describes how the lock is
applied. If <literal>block</literal> is used (the default),
the lock prohibits any of the requested operations without
time limit, and only privileged users may override it. If
<literal>delay</literal> is used, the lock can only delay the
requested operations for a limited time. If the time elapses,
the lock is ignored and the operation executed. The time limit
may be specified in
<citerefentry><refentrytitle>logind.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
Note that <literal>delay</literal> is only available for
<literal>sleep</literal> and
<literal>shutdown</literal>.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>--list</option></term>
<listitem><para>Lists all active inhibition locks instead of
acquiring one.</para></listitem>

doing so.</para>
