That is a combination that you really have to know to use, as --help
by itself doesn't tell you explicitly that it's even possible.

How hard is it to let --help show whether it's using multi-threading
or not?

Light green/cyan text on a light blue background? Unreadable. The
background also isn't centred on the page, while the text is, and the
HTML is broken (two  declarations, a  element inside
the  element). I'd never expect this to be official
documentation for any package.

Sorry to be so negative. I was (and am) very happy with the pointer to
enfuse-mp. It's just that making the software a bit clearer in the way
it presents information to the user is probably less work that having
this entire discussion.

Information is useful too.  And it's not documented in the canonical
places.

Why?  It seems there is stuff in there which can't be found
elsewhere.  Documentation shouldn't be optional.

I looked there too.  I've looked again.  There's no mention of the
online documentation at
http://enblend.sourceforge.net/enblend.doc/enblend_4.2.xhtml/enblend.html
there or anywhere else in that directory.  It should be there or in
the man/info pages.

I have:

 can build all documentation:  no, because of missing tidy

OK, I missed that one.  I didn't do the original port, and it's
possible that this got missed as a result.  I'll go through the README
and check what else I've missed.

Sorry, don't understand.

enfuse --help print what it does. 
"enfuse --version --verbose" print "only" some diagnostic information, e.g. 
with which libraries is was compiled. That's purely informative and can't 
be changed or influenced by the user.

The online documentation is created from the build system for convenience 
only. 
Each builder can create the documentation from the source.
The README contains a complete chapter "Documentation Generation". And the 
source contains a folder doc. So I don't know where you looked.
 
And for the builder configure reports at the end:

enblend-enfuse now configured for i686-pc-linux-gnu

 can build all documentation:  yes

So this is also no hint.

No, you misunderstand me:

You shouldn't have to run a program with almost undocumented
parameters to find out what it does.

Graphs and images can't.  But the texts can, and should.

I'd suggest that it's more of an attitude problem.  Incomplete man
pages don't help anybody.  There's no reference to some options, nor
to the online documentation.  It also claims that the info pages
(without graphs or images) are included in the info pages.  And I
can't find any reference to the online documentation in the build
instructions or any other file in the top level build directory.  How
did the Microsoft build people find out about it?

No wonder people are confused.

The content of the documentation (with graphs, images, code snippets, 
examples) can't be fitted into the format of the man pages.
Also the range of topics covered does not fit in layout of the man pages.

So this is a package problem.

It shouldn't be.  That's what man pages are for.  And the man page
doesn't even mention this combination of options.  I've only just
discovered:

  Extra feature: OpenMP: no

Output of "enfuse --version --verbose" and the description in chapter 3.1.1 
of the enblend/enfuse documentation (which should be installed) is not 
sufficient?

Using the OpenMP powered enfuse.

Running 8 instances of OpenMP-enfuse with 8 threads each one (as the 
multi-threaded enfuse does) (as your make -j8) spawns a lot of threads and 
is using a lot of memory.
So we prefer currently running only one multithreaded program at one time, 
and this is supported by hugin_executor.
