byte-compile-filebyte-compile-file is an interactive autoloaded compiled Lisp function in `
bytecomp.el'. (byte-compile-file FILENAME &optional LOAD) Compile a file of Lisp code named FILENAME into a file of byte code. The output file's name is generated by passing FILENAME to the function `byte-compile-dest-file' (which see). With prefix arg (noninteractively: 2nd arg), LOAD the file after compiling. The value is non-nil if there were no errors, nil if errors.
