The fcsh (Flex Compiler Shell) provides a shell environment for compiling applications, modules, and component libraries. It works similarly to mxmlc and compc, but compiles faster.
The Flex Compiler Shell (fcsh) compiles code faster than mxmlc and compc by keeping all the partial build objects in memory. It's similar to using the -incremental flag of mxmlc, but avoids having to load the JVM on each invocation. See the documentation for more information.
