### Guidelines & objectives:
# Target Python 2.7+ (but not 3)
# Use no non-default libraries (this may change in the future)
# Don't use SWORD bindings (this will probably change to allow *optional* use of bindings, if installed)
# Achieve full coverage of USFM according to UBS spec:
#      <http://paratext.ubs-translations.org/about/usfm>
# Employ best-practice conformant OSIS
# Employ modularity (functions rather than a big long script)
# Employ the same command-line syntax as usfm2osis.pl
# Use & abuse Unicode tags (http://unicode.org/charts/PDF/UE0000.pdf) to simplify Regex processing

### Roadmap:
# 0.5 initial commit, including full coverage of core USFM tags
# 0.6 test suite incorporating all USFM examples from UBS ICAP and other complex cases
# 0.x more clean-up & re-ordering to correctly encapsulate milestones within appropriate containers
# 0.x clean-up code: make fully OO? docstrings?
# 1.0 feature complete for release & production use
# 1.x xreffix.pl-functionality (osisParse(ref)), requiring SWORD bindings
# 1.x SWORD-mode output?
# 1.x IMP output?
# 1.x SWORD module output?, requiring SWORD bindings
