VFILE = .version

# The '^\#' is used instead of '^#' to circumvent a bug in older versions of
# Make (e.g GNU Make 4.2.1). However, the '^\#' sequence also causes a warning
# about a stray backslash in newer versions of grep (e.g. GNU grep 3.8) unless
# the -P option is used. Alternatively, the following Perl program may be used:
## VERSION := $(shell perl -n -e 'print unless /^\#/;' $(VFILE))
VERSION := $(shell grep -v -P '^\#' $(VFILE))
