antlr-skip-file-preludeantlr-skip-file-prelude is a compiled Lisp function in `
antlr-mode.el'. (antlr-skip-file-prelude SKIP-COMMENT) Skip the file prelude: the header and file options. If SKIP-COMMENT is non-nil, also skip the comment after that part. Return the start position of the file prelude. Hack: if SKIP-COMMENT is `header-only' only skip header and return position before the comment after the header.
