## 1.10 Akim
# * Inherit from symbols.ssh for \Alpha and the like
# * Make sure that specific rules are always _after_ generic rules
#   (see the \def section)
# * Cleaner handling of \begin et \end, \newcommand and the like
#   (as operators not sequences)
# * Highlight title given to environment (\begin{foo}[title])
# * Support (sub)*sections, chapter and part
## 1.9 Akim
# Case sensitive, updated to new syntax for closers, and requirement
## 1.8 Akim
# The prescript-like symbols are keywords, not operators.
# Put them as optional
