A client asked today why his RAL Studio application got so big.
The reason was (this time) not my plugin, but RBScript. For Mac OS X Intel, the plugin adds 958 KB to your application. With REAL Studio 2010r3 and newer REAL Software switched to LLVM which increases the plugin size to 10.5 MB.
If you care for download size of your application and you need RBScript, you may want to keep with older version.
It's the same decision people do when they use REAL Studio versions before 2008r2 to build Windows applications to avoid the libs folder.
