+NAME
+       compile-scheme - Compiling Scheme programs to executables
+
+SYNOPSIS
+       compile-scheme [-A path] [-I path] [-o path] input-file.sps
+
+       compile-scheme [-A path] [-I path] [-o path] input-file.scm
+
+       compile-scheme long-option
+
+DESCRIPTION
+       compile-scheme  is a tool to compile R6RS and R7RS Scheme programs.  It
+       supports most of SRFI-138 but also adds more features.
+
+       The program input-file is compiled into an executable  file.   The  re‐
+       sulting executable file is written to file specified by the -o path (if
+       present) or to the file named same as input-file but without  the  .scm
+       or .sps suffix.  On Windows either .bat or .exe is appended to the out‐
+       put name.
+
+SUPPORTED IMPLEMENTATIONS
+       Some implementations support both compiling and interpreting,  in  that
+       case  only the compiler functionality is used and the implementation is
+       marked as compiler.

+
+OPTIONS
+       -A path Append path to the list of directories that are searched in or‐
+       der to locate imported libraries.
+
+       -I path Prepend directory to the list of directories that are  searched
+       in order to locate imported libraries.
+
+       -o  output-file  Use  the  output-file file, instead of the default de‐
+       ducted from input-file, for the executable file produced.
+
+       Multiple instances of the -A, and -I options can be specified.
+
+       --list-r6rs List supported R6RS implementations.
+
+       --list-r7rs List supported R7RS implementations.
+
+       --list-all List all supported implementations.
+
+       --version Show the software version.  --debug Turn on debug output.
+
+       --help Shows you command to read this manual page. :)
+
+ENVIRONMENT
+       COMPILE_R7RS
+
+       COMPILE_SCHEME
+
+              Either of these environment variables must be set.   Set  either
+              to  the  name  of the implementation as specified in the support
+              list.  This differs from SRFI-138 as the SRFI excepts a path.
+
+       COMPILE_SCHEME_DEBUG
+
+              Another way in addition to --debug to turn on debug output.
+
+STANDARDS
+       SRFI    138:    Compiling    Scheme    programs     to     executables.
+       https://srfi.schemers.org/srfi-138/srfi-138.html
+
+CAVEATS
+       Differences from SRFI-138
+
+              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
+
+              Only supports one input-file.
+
