From: "W. Trevor King" <wking@tremily.us> Gentoo's dev-python/docutils-0.10 installs Docutils scripts with a *.py extension, so I have /usr/bin/rst2man.py and no rst2man script. This patch supports users with both types of systems by checking for rst2man, falling back on rst2man.py, and giving up only if neither is found. Users can also set the new RST2MAN path variable explicitly when they call Make: make RST2MAN=/my/custom/rst_to_man_converter build-man We pass the configured RST2MAN path through to prerst2man.py to use in its system call. We can use a non-empty RST2MAN to check for the availability of an rst2man program, so there's no need for a separate HAVE_RST2MAN. However, we keep the existing HAVE_RST2MAN for consistency with HAVE_SPHINX. --- At the risk of bike-shedding, rewrite the configure check to be more "obvious". This is pretty subjective, but in particular I'm not a big fan of resetting RST2MAN at the bottom of every iteration of the for loop. Also conform a bit more to the convention of using a lower case variable in configure and assigning it in Makefile. For some reason it bugs me a bit to pass RST2MAN as an extra command line argument, but I guess taking some arguments by command line and some by environment variables would also be icky. configure | 23 ++++++++++++++++------- doc/Makefile.local | 2 +- doc/prerst2man.py | 9 +++++---- 3 files changed, 22 insertions(+), 12 deletions(-) diff --git a/configure b/configure index 137acea..fdf5bad 100755 --- a/configure +++ b/configure @@ -444,21 +444,27 @@ else fi printf "Checking if sphinx is available and supports nroff output...
