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>

<listitem><para>Takes either <literal>block</literal> or

the lock prohibits any of the requested operations without

time limit, and only privileged users may override it. If

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
