Installing the Windows Plugin ============================= 1) Start with untaring the file into the plugins directory. Here is a example for the 1.5 version of the Windows plugin. $ cd plugins $ tar -zxvf windows-1.5-1.4.tar.gz 2) If you have SquirrelMail version 1.4.1 or newer, skip to step 4 3) Determine if you want to patch the SquirrelMail source code for this plugin. Testing has shown this plugin will work without any patching, but there is one minor problem that could create errors in isolated circumstances. If you want to be sure to avoid such errors, run the included patch: $ patch -p0 < windows/read_in_new_window_patch.squirrelmail-1.4.0.diff If the output of this command indicates any FAILUREs, you either need to update the patch utility on your system or you have some non-standard/modified SquirrelMail source code; we can work together to get your version patched - just send an email. Note for Windows users: you can get native patch functionality by installing this very useful package: http://unxutils.sourceforge.net/ 4) Then go to your config directory and run conf.pl. Choose option 8 and move the plugin from the "Available Plugins" category to the "Installed Plugins" category. Save and exit. $ cd ../config/ $ ./conf.pl Upgrading the Windows Plugin ============================ 1) Just untar the file into the plugins directory.
