This is in reply to Peter Seebach's question; solon.com does not appear
to work.

| A question for you:  Is there a target for "build if necessary and
| then install"?  I've discovered that my 3/60 takes just over half an
| hour just to descend the entire tree; 'make all install' is thus about
| half an hour slower than 'make all-install' would be.  Not a *huge*
| difference, but enough to notice.
| 
| I appreciate the warning.  I have a *lot* of weird make problems.

If you have BUILD set, 'make install' will make things that are out
of date before installing them. If you have UPDATE set, then 'make install'
will only install newer things.
