+A small collection of perl extensions for the rxvt-unicode terminal emulator.
+
+Installation
+------------
+Simply place the scripts you want to install in the /usr/lib/urxvt/perl/ folder
+for system-wide availability. You can also put them in a folder of your
+choice, but then you have to add this line to your .Xdefaults:
+
+    URxvt.perl-lib: /your/folder/
+
+See the following sections for information on how to enable the scripts or set
+script-specific options and keyboard mappings in your .Xdefaults.
+
+
+keyboard-select
+---------------
+Use keyboard shortcuts to select and copy text.
+
+After installing, put the folling lines in your .Xdefaults:
+
+    URxvt.perl-ext-common: ...,keyboard-select
+    URxvt.keysym.M-Escape: perl:keyboard-select:activate
+
+Use Meta-Escape to activate selection mode, then use the following keys:
+
+    h,left:  move cursor left
+    j,down:  move cursor down
+    k,up:    move cursor up
+    l,right: move cursor right
+    v:       toggle normal selection
+    V:       toggle linewise selection
+    Ctrl-v:  toggle blockwise selection
+    y:       copy selected text to primary buffer and quit selection mode
+    Escape:  cancel whole keyboard selection mode
+
+
+url-select
+----------
+Use keyboard shortcuts to select URLs.
+
+This should be used as a replacement for the default matcher extension, it also
+makes URLs clickable with the middle mouse button.
+
+After installing, put the folling lines in your .Xdefaults:
+
+    URxvt.perl-ext-common: ...,url-select
+    URxvt.keysym.M-u: perl:url-select:select_next
+
+Use Meta-u to activate URL selection mode, then use the following keys:
+
+    k:      select next upward URL (also with Meta-u)
+    j:      select next downward URL
+    Return: open selected URL in browser and quit selection mode
+    y:      copy (yank) selected URL and quit selection mode
+    Escape: cancel URL selection mode
+
+Options:
+
+    URxvt.urlLauncher:   browser/command to open selected URL with
+    URxvt.underlineURLs: if set to true, all URLs get underlined
+
+
+clipboard
+---------
+Use keyboard shortcuts to copy the selection to the clipboard and to paste the
+clipboard contents (optionally escaping all special characters).
+
+Requires xsel to be installed!
+
+After installing, put the folling lines in your .Xdefaults:
+
+    URxvt.perl-ext-common: clipboard
+    URxvt.keysym.M-c:   perl:clipboard:copy
+    URxvt.keysym.M-v:   perl:clipboard:paste
+    URxvt.keysym.M-C-v: perl:clipboard:paste_escaped
+
+The use of the functions should be self-explanatory!
