-Subject: avoid segfault in internal help parser
-
-the dummy help parser has a maximum length of index entries that is
-too short. Increase the constant to avoid that.

-Subject: tag more examples
-
-Add a way to tag all examples from a .lib file included.
-
-Use this new feature to tag some libs needed external programs,
-special features or significant memory usage in order to be able
-to build documentation on more machines.
-
-Make DOC2TEX_EXAMPLE_EXCLUSIONS a make variable, so that this
-setting can also be overridden at make invocation time.
-
-Bug: http://www.singular.uni-kl.de:8002/trac/ticket/409

++* must be found to circumvent the sequence of a()'s growing to a ridiculous size.
++* Therefore: We use (a(),a(),dp,C) for the computation of the reduced basis. But then we
++* do have an interior point of the cone by adding the extremal rays. So we replace
++* the latter cone by a cone with (a(sum_of_rays),dp,C).
++* Con: It's incredibly ugly

-From: Felix Salfelder <felix at salfelder.org>
-Date: Thu, 16 Feb 2012 12:37:00 +0100
-Subject: miscellaneous Makefile.in patches
-
- - fix flags (mostly search paths)
- - repair default and install targets
- - remove dependency on mod2.h in kernel. "make depend" works fine

+Subject: default path settings
+
+- Hardcode "Singular" pathname, so we can install the library to a
+ different location than the binaries.
+- as S_BIN_DIR and S_ROOT_DIR are the same in the Debian package,
+ don't default ROOT_DIR to BIN_DIR/..
+- xterm set as x-terminal-emulator alternative.
+- emacs binary located in /usr/bin
+- remove %b/.. and %r/.. from default search path in order to
+ not look into /usr/lib/LIB for libraries.

-Subject: default path settings
-
-- Hardcode "Singular" pathname, so we can install the library to a
- different location than the binaries.
-- as S_BIN_DIR and S_ROOT_DIR are the same in the Debian package,
- don't default ROOT_DIR to BIN_DIR/..
-- xterm set as x-terminal-emulator alternative.
-- emacs binary located in /usr/bin
-- remove %b/.. and %r/.. from default search path in order to
- not look into /usr/lib/LIB for libraries.
