fixdepend takes the Makefile generated by makedepend and produces a new
Makefile which has the library .o's depending on the .h files rather than
on the .c's.  This allows a makefile to be easily constructed which generates
libraries without having to keep .o files around outside of the library.
This saves space and is avoids clutter in the makefile itself.

Xb) To build fixdepend, just edit the makefile and set the bindir and mandir's,
X   then type 'make install'.
X
X   This program has been tested on Dec and Sun platform's, using the GNU make
X   program.

X          Good Luck!

X.I fixdepend
Xtakes the Makefile generated by
X.I makedepend
Xand produces a new Makefile which has the library .o's depending on the .h
Xfiles rather than on the .c's.  This allows a makefile to be easily constructed
Xwhich generates libraries without having to keep .o files around outside of
Xthe library.  This, understandably, saves space and is avoids clutter in the
Xmakefile itself.
X
X.SH OPTIONS
X.IP "-l <library>" 4
XSpecifies the library name to use in the dependency line.
X.IP "-f <Makefile>"
XAllows the use of varied makefile names, the default is
X.I Makefile.
X.IP "-s <makedepend-separator-line>"
XAllows the use of non-standard separator lines.  the default is
X
X # DO NOT DELETE THIS LINE -- make depend depends on it.
