# With the settings here, latexmk can be used to process texinfo files
# (typical extension .texi) to pdf files, including the making of
# indices. This version uses a newly documented internal routine
# of latexmk.

###!!!!!!!!! NOTE THAT THE NAMES OF THE INDEX FILES ARE POSSIBLY
### SUBJECT TO CHANGE IN FUTURE VERSIONS OF texinfo.
### The configuration provided by this file was valid in
### September 2015. (The file texinfo.tex had version
### 2015-07-01.07.)
