+Retain newlines and comments unmodified;
+@item
+Be clever about using the available horizontal space while not overflowing the

+@item
+Be clever about aligning things horizontally (this can be turned off
+completely however);
+@item
+Have linear complexity in the size of the input.

+ (description "This package is similar to the optparse-applicative package,
+but less features, more flexibility and more evil.
+
+The main differences are:
+
+@itemize
+@item Provides a pure interface by default
+
+@item Exposes an evil monadic interface, which allows for much nicer binding
+of command part results to some variable name.
+
+In optparse-applicative you easily lose track of what field you are modifying
+after the 5th <*> (admittedly, i think -XRecordWildCards improves on that
+issue already.)
+
+Evil, because you are not allowed to use the monad's full power in this case,
+i.e. there is a constraint that is not statically enforced. See below.
+
+@item The monadic interface allows much clearer definitions of commandparses
+with (nested) subcommands. No pesky sum-types are necessary.
