I got a warning when I, with the latest TeX Live, ran

$ cluttex --engine=pdflatex

against a LaTeX file that has:

\usepackage{xparse}

The error message said

[DIAG] The driver option for expl3 is missing or wrong.
[DIAG] Consider setting 'driver=pdfmode' option when loading expl3.

However this warning is no longer valid since l3backend has received its updates and we have l3backend-pdftex.def, l3backend-luatex.def, and l3backend-xetex.def instead of l3backend-pdfmode.def and l3backend-xdvipdfmx.def. A pull request that will fix this will follow.

最新のTeX Live で expl3 を読み込む LaTex file を clpdflatex すると expl3 のドライバミスマッチエラーがでます．これは l3backend のドライバ名が pdfmode -> pdftex, luatex および
xdvipdfmx -> xetex と変わったためだと思われます．PR投げて修正しますが，Luaは不慣れなのでお助けいただけるとありがたいです．

Ad-hoc fix for expl3 driver detection: l3backend renamed
8a528ae 
l3backend, i.e. expl3's driver-specific backend, got renamed as
l3backend-pdfmode -> l3backend-pdftex, l3backend-luatex
l3backend-xdvipdfmx -> l3backend-xetex.

This caused cluttex to unnecessarily warn user for mismatched driver
setup for expl3, as reported in
minoki#5.
With this commit, in order to fix this, cluttex will
additionally detect the load of l3backend-pdftex, luatex and xetex.
