+Clang attempts to guess file names based on the OS and distro (yes!),
+but unfortunately, that doesn't work for us.
+
+This patch makes it easy to insert libc's $libdir so that Clang passes the
+correct absolute file name of crt1.o etc. to 'ld'.  It also disables all
+the distro-specific stuff and removes the hard-coded FHS directory names
+to make sure Clang also works on non-Guix systems.

+     "Grandalf is a Python package made for experimentations with graphs
+drawing algorithms.  It is written in pure Python, and currently implements
+two layouts: the Sugiyama hierarchical layout and the force-driven or energy
+minimization approach.  While not as fast or featured as graphviz or other
+libraries like OGDF (C++), it provides a way to walk and draw graphs no larger
+than thousands of nodes, while keeping the source code simple enough to tweak
+and hack any part of it for experimental purpose.  With a total of about 1500
+lines of Python, the code involved in drawing the Sugiyama (dot) layout fits
+in less than 600 lines.  The energy minimization approach is comprised of only
+250 lines!
+
+Grandalf does only 2 not-so-simple things:
+@itemize
+@item computing the nodes (x,y) coordinates (based on provided nodes
+dimensions, and a chosen layout)
+@item routing the edges with lines or nurbs
+@end itemize
+
+It doesn’t depend on any GTK/Qt/whatever graphics toolkit.  This means that it
+will help you find where to draw things like nodes and edges, but it’s up to
+you to actually draw things with your favorite toolkit.")
