makefile dependency-list creator

[Mike Roberson]

[ peel back foil to expose tater tots ]

If you've ever gone thorugh a marathon typing session of entering a
program from memory, you realize it's tough figuring out the makefile
dependency lists for your program.  Well, herein lies an automated
means of laziness.

These scripts, (odeph and hdepo), create makefile dependency-lists.
The input to these scripts is as in the following example.

	Given the input as:

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

#! /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.

	Given the input as:

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