USAGE="Usage: $0 [-r] file1 file2 ... file3 Program

	Will compile a JTalk Program.js file by concatenating listed files:

          *.js files are concatenated as is. If not found we look in $JTALK/js
          *.st files are compiled into .js files. If not found we look in $JTALK/st.
          Each file is considered to be a single class category of the same name.

        NOTE: boot.js and Kernel.js is always first and init.js
              is always added just before the last file. Finally main.js is added if found.
