The integration library libgtkmacintegration.dylib contains two implementations, the original one using Carbon (gtk-mac-integration) and a new one using Cocoa (GtkOSXApplication). Since Apple has deprecated Carbon in OSX 10.6 (Snow Leopard), gtk-mac-integration is also now deprecated and should not be used in new code. Furthermore, maintainers of existing Gtk-OSX ports which use gtk-mac-integration are strongly encouraged to convert to GtkOSXApplication. In addition to being 64-bit compatible, it also fixes some glaring bugs in gtk-mac-menu when using multiple windows.

TTF2PT1 is a modification of Andrew Weeks TTF2PFA True Type to Postscript Type 3 converter. Which will convert Most True Type Fonts to an Adobe Type 1 .pfa file. And also the other font formats supported by the FreeType library to an Adobe Type 1 .pfa file. And the BDF fonts to an Adobe Type 1 .pfa file. Yet another use is as a hinting engine: feed it an unhinted or poorly hinted Adobe Type 1 font through the FreeType library and get it back with freshly generated hints. If you want .pfb files, don't despair: they can be produced too. The files produced by default are in human readable form, which further needs to be encoded with the t1utilities, to work with most software requiring type 1 fonts. But for the lazy people ttf2pt1 includes a built-in portion of t1utilities as well.

Quick startup, by using a JVM process running in background GroovyServ reduces startup time of the JVM for runnning Groovy significantly. It depends on your environments, but in most case, it’s 10 to 20 times faster than regular Groovy. Features GroovyServ provides following features: Quick startup of Groovy script (about 10 to 20 times much). Transparent server operation. If a server is not running when a client is invoked, the client runs a server in background. System.in/out/err is available through a socket stream. Trap a call of System.exit() and send the exit status to the client Server process keeps working. Signal handling on a client side. Ctrl-C terminates only a client process. Changes a current working directory as appropriately as possible. Automatic propagation of a CLASSPATH environment variable from a client to a server. Selectable propagation of any environment variables from a client to a server. User commands written by Go programming language. Works on Linux, Mac and even Windows without Cygwin. License GroovyServ is released under the Apache 2.0 License.
