Remove -S for the install usage message
Make the install usage message < 80 columns wide
Place the dodir declaration in order.

Implement -d in install. Update the man page to reflect this change.

Use EX_* exit values, from NetBSD

Changed 'd' to 'D' in getopt arg too.

Per discussions in -current

	- Change the debug flag from -d to -D to avoid conflict with other
	  install programs.
	- Update man page to reflect this
	- Update usage string
-d meaning creat directory is specifically not implemented by these changes.

Be more careful with mmap. If it fails, fall back to a plain compare or

copy.

Dont leave stray INS@xxxx temp files around, especially when installing
something less than 8MB and the destination runs out of space, etc.

It still doesn't clean up the temp files on SEGV or other signals etc.

accidently removed the "dont compare > 8MB files hack".

didn't rewind the files after the read()s in the non-mmap compare.

Only attempt to mmap() files from a ufs or cd9660 fs for comparing or

installing.  mmap'ing stuff over a nfs mount took out my machine during
a 'make world' last night while I was asleep.  I started out with a list
of fs's to avoid, when I realised that I really didn't know which ones
were safe with mmap, so I went for the ones I knew and implemented a
fallback compare.

Add a simple -v (verbose) option that allows you to see when -C actually

installs something.  This is not 100% right, since it has a false hit
when install -C snaps hard links.

Also, run strip(1) from the $PATH, otherwise you need a special version
of install to install (say) elf binaries which have a different strip.
With JDP's elfkit, the layout of the path determines which binary format
you are generating.
