Comment(by mpatel):

 I think we need to list eclib headers for these modules, so that during an
 upgrade, if the eclib package is rebuilt, because eclib and/or a dependent
 package has changed, the modules are also rebuilt.  Is this correct?

 I see
 {{{
 #!sh
 $ cd sage-4.6.rc0/devel/sage/sage/libs/mwrank
 $ grep "eclib/" *.c* *.h
 wrap.cc:#include "eclib/htconst.h"
 wrap.cc:#include "eclib/interface.h"
 wrap.h:#include "eclib/curve.h"
 wrap.h:#include "eclib/egr.h"
 wrap.h:#include "eclib/descent.h"
 wrap.h:#include "eclib/points.h"
 wrap.h:#include "eclib/isogs.h"
 wrap.h:#include "eclib/marith.h"
 wrap.h:EXTERN void two_descent_saturate(struct two_descent* t, long
 sat_bd); // = -1 for default set in eclib/src/qcurves/saturate.h
 (currently 100)
 }}}
 and
 {{{
 #!sh
 $ cd sage-4.6.rc0/devel/sage/sage/libs/cremona
 $ grep "eclib/" *.cpp | grep -v cdef
 homspace.cpp:#include "eclib/moddata.h"
 homspace.cpp:#include "eclib/symb.h"

 }}}
 For `homspace` and `mat`, do we need to mention in `module_list.py` the
 `eclib/` headers that aren't listed above?
