 == Special Update/Build Instructions ==
 
-See spkg-src.
+See spkg-src to create the source tarball.
 
-== Patches ==
- * assert.patch: logic seems to be broken on some platforms
- * Minor.h.patch: needs to have <time.h> included on Cygwin
- * slibdir.patch: set default slibdir to ${datarootdir}/singular
-   instead of ${prefix}/LIB, see #13344.
- * sanitize_gmp_header_hack.patch:
-   Fix and simplify generation of `factory/cf_gmp.h` (cf. #14737).
- * flint.patch: avoid underlinking FLINT in libsingular.
- * exeext.patch: Add $(EXEEXT) to some executable names.
- * cygwin64.path: Support for Cywgin64.
- * templates.patch: do not use -fno-implicit-templates, which breaks
-   the build with NTL 6.2.1 for some GCC versions.
-
-The following patches fix errors that only occur in a debug build, see
-http://trac.sagemath.org/ticket/16938
-They shouldn't be needed any more in the next Singular version:
-
- * hans-polyvectorerror.patch: Fix erroneous "mixed poly/vector" error
-   message
- * hans-slimgb-and-letterplace.patch: Fix incorrect debug assertions
-   in slimgb and letterplace algebras
- * hans-integerpolys.patch: Fix incorrect assertions in integer
-   polynomials.

-Other notes
- * The option '--without-dynamic-kernel' is used on *all*
-   systems with the exception of Linux. The online README at
-   http://www.singular.uni-kl.de/svn/trunk/README says this should
-   be used on Solaris, with no mention of it being necessary for
-   OS X, or any other platform except Solaris.
- * The online readme says that CONFIG_SHELL should be set to /bin/bash
-   on Solaris. This is not done currently. Since this does not build
-   fully as a 64-bit application on Solaris, CONFIG_SHELL should be
-   investigated as a possible cause later.
- * Be sure that Singular/Singular.rc.in is present, as occasionally this
-   was missing, which caused problems on Cygwin (e.g., see #10235)
+Other notes:
  * Due to http://www.singular.uni-kl.de:8002/trac/ticket/438, we
    currently always build Singular with its debug code.  Change
    --with-debug to $WITH_DEBUG in the configure call if this is fixed.
