#   elvis may crash on some systems without this setting in sh environment

#   other (old) programs (not elvis) crash without something like this:

# What is vi?  Elvis is a vi(1) (visual ed) vi text editor variant (vim is another variant). "vi" is short for "visual ed(1)" (the 1 means see manpage for ed in section 1 of unix manual pages). vi as a visual editor means typical keyboard editing with ed(1) accessible to do complex editing jobs.  (Elvis is by Steve Kirkendall in the 200's, a variant of vi(1) by Bill Joy that appeared in BSD, 1979)

# Elvis builds using autoconfig style build, however because it's a little
# older (also less hacked), the following would be done to build it on newer
# systems that "disobey older rules".

# the below is actually an excerpt from script 'build' found in

# https://sourceforge.net/projects/x-lfs-2010/files/build-0.1.11.tar.gz/download

# (however the below has addition for Apple Sierra OS that will be in 1.12)
