You have to show him how to catch the first fish!

It does vary: the start of it looks like this:

SYNOPSIS
      a68g [          |        |        [string]] [             | 
         ]

It turns out that all option names in this summary and in the 
elaborations later on, are blanked. Apparently they are displayed in a 
light-grey text, which is also the background colour of my console window!

I get similar problems with Clang when it displays error messages; I 
have to capture to a file to find what's wrong.

I don't get that with gcc, since it sets the background to black, but 
then doesn't bother restoring it afterwards. You'd think these programs 
would get the easy stuff right! Especially given the vast numbers of 
users that can give feedback.

I think the available options are messy. '--rerun' is used with A68G 
with a .a68 input, which somehow lets it use a cached version, but the 
details are not clear.

--compile is used to create a persistent intermediate version, in the 
form of a binary .sh file, which is run directly without needing A68G 
(or not needing to type it).

If you do use --listing etc, then it first /runs/ the program before it 
generates the output files, which is unexpected (and a little annoying 
if it takes some time to finish).

So I think the options could be presented more cleanly and perhaps 
segregated. Here is example help text from one of my compilers when 
invoked as 'mm -help':

------------------------------------------------
c:\mx>mm -help
M Compiler for 64-bit Windows

Normal use:           Compiles lead module prog.m to:

     mm      prog      prog.exe (default)
     mm -r   prog      in-memory native code then execute
     mm -i   prog      in-memory IL then interpret

     mm -exe prog      prog.exe
     mm -dll prog      prog.dll
     mm -obj prog      prog.obj
     mm -a   prog      prog.asm (aa/nasm/gas, depends on config)
     mm -mx  prog      prog.mx  (private executable format)
     mm -p   prog      prog.pcl (textual IL)
     mm -ma  prog      prog.ma  (single amalgamated source file)
     mm -c   prog      prog.c   (single C source file)

Other options:
     ....
------------------------------------------------

(There are half a dozen more options that might be useful to someone 
other than the developer.

I added that -c option just now. Normally a separate program is used to 
transpile to C; using that here will just invoke that other program.)
