I've modified the dependency-list creator to handle "include <lib1/lib2/..>"
more appropriately. The new version checks <inc> files against a list of
directories, hopefully compatible with the cc(1) list, to determine the
full pathnames, which are included in the output dependency files.

I used the original distribution packaging. I hope it works!
Be nice, this is my first submission.

#! /bin/sh
export PATH || (echo "You didn't use (Bourne) sh, you bip!" ; kill $$)
#
DEPENDENCY=${1-HOME/bin}
echo "all files will be put in the directory \"$DEPENDENCY\", ok? (<rub> = no)\c"
read foople
#
echo $DEPENDENCY/READ.ME
cat >$DEPENDENCY/READ.ME <<'!DONE!READ.ME!BIP!'

1) Run dep_init to install the files in a certain directory, as:

	dep_init $HOME/bin
which expands "$HOME/bin" and substitutes it for '$DEPENDENCY' in each file;
or:
	dep_init '$HOME/bin'
which substitutes '$HOME/bin' for '$DEPENDENCY' in each file.

2) Then run dep_mv as:

	dep_mv $HOME/bin
but not as:

	dep_mv '$HOME/bin'

These scripts take input as in the following example.
( In the examples that follow, <lib> is an optional argument corresponding
  to the "inclib" part of the cc(1) "-Iinclib" option.
  The name of the standard library "/usr/include" is hardcoded into the file
  "dep.pass2.sh" 
)

	Given the input as:

		grep include *.c | odeph <lib> >ch.mk
		grep include *.c | hdepo <lib> >hc.mk

	or a file, (dotc), containing:

		file1.c:#include <stdio.h>
		file1.c:#include <filea.h>
		file2.c:#include <stdio.h>
		file2.c:#include "fileb.h"
		file3.c:#include <stdio.h>
		file3.c:#include <filea.h>
		file4.c:#include <stdio.h>
		file4.c:#include <filea.h>
		file4.c:#include "fileb.h"
		file5.c:#include <stdio.h>
		file5.c:#include "fileb.h"

	redirected into the scripts, as:

		odeph <lib> <dotc >ch.mk
		hdepo <lib> <dotc >hc.mk

	The script 'odeph' produces a makefile dependence list, (ch.mk),
	of the form:
		file1.o : stdio.h filea.h

		file2.o : stdio.h fileb.h

		file3.o : stdio.h filea.h

		file4.o : stdio.h filea.h fileb.h

		file5.o : stdio.h fileb.h

	The script 'hdepo' produces a makefile dependence list, (hc.mk),
	of the form:
		file1.o file3.o file4.o : filea.h

		file2.o file4.o file5.o : fileb.h

		file1.o file2.o file3.o file4.o file5.o : stdio.h
