-NAME
-       compile-r7rs - a tool to compile R6RS and R7RS Scheme programs
-
-ENVIRONMENT
-       COMPILE_R7RS  environment variable must be set to the name of the imple‐
-       mentation as specified in the support list.   **This  differs  from  the
-       SRFI** as the SRFI excepts a path.
-
-SYNOPSIS
-       compile-r7rs [-n BITS] [--bits BITS] file...  compile-r7rs
-
-DESCRIPTION
-       compile-r7rs
-
-       It  aims  to support Scheme SRFI-138 - Compiling Scheme programs to exe‐
-       cutables.
-
-CAVEATS
-       -      No support for -D flag.
-
-       -      Not all implementations support adding to  beginning  or  end  of
-              load path so -I and -A might work the same
-
-OPTIONS
-       -n, --bits=BITS Set the number of bits to modify.  Default is one bit.
-
-                                                                compile-r7rs(1)
