Hi, Paul
I should have mentioned that this series is rebased to the current master
431a80df9d6e ("Fix build error on Fedora 23 with texlive").
Regarding to ("[PATCH v2 2/3] Improve behavior of build scripts"), I
want to add some comments in the form of a reply to your previous feedback.
As I refactored the script, please note that in-line comments do not
exactly match the actual patch.

I checked several intentional error cases for this patch. However, I'm
sure you are the one who will use the scripts most heavily, you might
find corner cases I'm not aware of.

I've not gone so far as to distinguish whether a warning is of a quick-quiz
link or not, but I think current level of output should be quite useful
for most of the cases. Please give it a try.

Done.
And I made a change so that the giving-up of the iteration is decided
by the result of comparison of recent two logs. When they have identical
warnings, giving-up logic kicks in (note that there are special cases
mentioned in the commit message) and the remaining warning messages will be
displayed. The messages should contain the info of undefined symbols.

As for the bibtex part moved to Makefile, I made '.bbl' be dependent
on '.aux.'
'.aux' requires pdflatex to run for the first time, so I separated
'runfirstlatex.sh.' Since '.aux' is always updated by pdflatex, this
means that bibtex is always invoked for a normal 'make.'
If you absolutely want bibtex *not* to run (and you are sure that '.bib'
files are not modified), touch a related '.bbl' file just before a 'make'.
Then 'runfirstlatex.sh' won't be invoked. But I think bibtex itself is
fairly quick, and simply doing 'make' is acceptable. Please give it a try
and let me know how it feels like.
I also made changes in the comment area at the head of each script. I added
my copyright notices there, but not sure if those are what are expected.
Could you please give a look at them, too?
Thanks, Akira
