LIBEMF2SVG_VERSION =

Gem version follows the pattern:

{LIBEMF2SVG_VERSION}.{LIBEMF2SVG_RUBY_ITERATION}

where LIBEMF2SVG_VERSION is the upstream libemf2svg release this gem is built against, and LIBEMF2SVG_RUBY_ITERATION is a counter for Ruby-side changes (recipe bug fixes, CI changes, docs) that bump without a new libemf2svg release. The iteration resets to 0 each time LIBEMF2SVG_VERSION bumps.

See README.adoc -> "Versioning" for the rationale and examples.

"1.8.2"
LIBEMF2SVG_RUBY_ITERATION = 
1
VERSION = 
"#{LIBEMF2SVG_VERSION}.#{LIBEMF2SVG_RUBY_ITERATION}"
