+\H{pageant-cmdline} The Pageant command line
+
+Pageant can be made to do things automatically when it starts up, by
+specifying instructions on its command line. If you're starting
+Pageant from the Windows GUI, you can arrange this by editing the
+properties of the Windows shortcut that it was started from.
+
+\S{pageant-cmdline-loadkey} Making Pageant automatically load keys
+on startup
+
+Pageant can automatically load one or more private keys when it
+starts up, if you provide them on the Pageant command line. Your
+command line might then look like:
+
+\c C:\PuTTY\pageant.exe d:\main.key d:\secondary.key
+
+If the keys are stored encrypted, Pageant will request the
+passphrases on startup.
+
+\S{pageant-cmdline-command} Making Pageant run another program
+
+You can arrange for Pageant to start another program once it has
+initialised itself and loaded any keys specified on its command
+line. This program (perhaps a PuTTY, or a WinCVS making use of
+Plink, or whatever) will then be able to use the keys Pageant has
+loaded.
+
+You do this by specifying the \c{-c} option followed by the command,
+like this:
+
+\c C:\PuTTY\pageant.exe d:\main.key -c C:\PuTTY\putty.exe
