 FREQUENTLY ASKED QUESTIONS
+    The new selection selects pieces that are too big, how can I select
+    single words?
+        Yes. For example, if you want to select alphanumeric words, you can
+        use the following resource:
+           URxvt.selection.pattern-0: ([[:word:]]+)
+        If you click more than twice, the selection will be extended more
+        and more.
+        To get a selection that is very similar to the old code, try this
+        pattern:
+           URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
+        Please also note that the *LeftClick Shift-LeftClik* combination
+        also selects words like the old code.
+    I don't like the new selection/popups/hotkeys/perl, how do I
+    change/disable it?
+        You can disable the perl extension completely by setting the
+        perl-ext-common resource to the empty string, which also keeps
+        rxvt-unicode from initialising perl, saving memory.
+        If you only want to disable specific features, you first have to
+        identify which perl extension is responsible. For this, read the
+        section PREPACKAGED EXTENSIONS in the rxvtperl(3) manpage. For
+        example, to disable the selection-popup and option-popup, specify
+        this perl-ext-common resource:
+           URxvt.perl-ext-common: default,-selection-popup,-option-popup
+        This will keep the default extensions, but disable the two popup
+        extensions. Some extensions can also be configured, for example,
+        scrollback search mode is triggered by M-s. You can move it to any
+        other combination either by setting the searchable-scrollback
+        resource:
+           URxvt.searchable-scrollback: CM-s
     Isn't rxvt supposed to be small? Don't all those features bloat?
         I often get asked about this, and I think, no, they didn't cause
         extra bloat. If you compare a minimal rxvt and a minimal urxvt, you
         can see that the urxvt binary is larger (due to some encoding tables
         always being compiled in), but it actually uses less memory (RSS)
         Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k),
         this still fares rather well. And compared to some monsters like
         gnome-terminal (21152k + extra 4204k in separate processes) or
         konsole (22200k + extra 43180k in daemons that stay around after
-        exit, plus half aminute of startup time, including the hundreds of
+        exit, plus half a minute of startup time, including the hundreds of
         warnings it spits out), it fares extremely well *g*.
     Why C++, isn't that unportable/bloated/uncool?
         Is this a question? :) It comes up very often. The simple answer is:
         I had to write it, and C++ allowed me to write and maintain it in a
         For other problems that also affect the Debian package, you can and
         probably should use the Debian BTS, too, because, after all, it's
         also a bug in the Debian version and it serves as a reminder for
         other users that might encounter the same issue.
+    I am maintaining rxvt-unicode for distribution/OS XXX, any
+    recommendation?
+        You should build one binary with the default options. configure now
+        enables most useful options, and the trend goes to making them
+        runtime-switchable, too, so there is usually no drawback to enbaling
+        them, except higher disk and possibly memory usage. The perl
+        interpreter should be enabled, as important functionality (menus,
+        selection, likely more in the future) depends on it.
+        You should not overwrite the "perl-ext-common" snd "perl-ext"
+        resources system-wide (except maybe with "defaults"). This will
+        result in useful behaviour. If your distribution aims at low memory,
+        add an empty "perl-ext-common" resource to the app-defaults file.
+        This will keep the perl interpreter disabled until the user enables
+        it.
+        If you can/want build more binaries, I recommend building a minimal
+        one with "--disable-everything" (very useful) and a maximal one with
+        "--enable-everything" (less useful, it will be very big due to a lot
+        of encodings built-in that increase download times and are rarely
+        used).
+    I need to make it setuid/setgid to support utmp/ptys on my OS, is this
+    safe?
+        Likely not. While I honestly try to make it secure, and am probably
+        not bad at it, I think it is simply unreasonable to expect all of
+        freetype + fontconfig + xft + xlib + perl + ... + rxvt-unicode
+        itself to all be secure. Also, rxvt-unicode disables some options
+        when it detects that it runs setuid or setgid, which is not nice.
+        Besides, with the embedded perl interpreter the possibility for
+        security problems easily multiplies.
+        Elevated privileges are only required for utmp and pty operations on
+        some systems (for example, GNU/Linux doesn't need any extra
+        privileges for ptys, but some need it for utmp support). It is
+        planned to mvoe this into a forked handler process, but this is not
+        yet done.
+        So, while setuid/setgid operation is supported and not a problem on
+        your typical single-user-no-other-logins unix desktop, always
+        remember that its an awful lot of code, most of which isn't checked
+        for security issues regularly.
     When I log-in to another system it tells me about missing terminfo data?
         The terminal description used by rxvt-unicode is not as widely
         available as that for xterm, or even rxvt (for which the same
         problem often arises).

         Removes any support for resource checking.
-    --enable-xgetdefault
-        Make resources checking via XGetDefault() instead of our small

-        Please note that nowadays, things like XIM will automatically pull

         Add support for our possibly faster memset() function and other
