Merge pull request #5 from whitequark/master

Fix typo in ocamlbuild plugin
Unified parsing rules for if/else and if/elif into if/elif/else. It is
now possible to have both #else and #elif in the same #if/#endif block.
Version 1.0.1
Removed useless "Author" section from the readme.
Initial support for tuples in comparisons. Tuples can be constructed and
compared. Variables are still limited to ints.
Slightly better support for int tuples: they may now come from a
variable. However, variables must expand directly into an int literal or
a tuple of int literals. Doing more than that well is beyond the scope
of this application.
Work in progress. Requires version string parsing.
New option -V for parsing the components of a version string and make
them available as variables.
.ocp-indent file for better indentation.
Formatting: no more tabs or trailing space
Some documentation for the new -V option.
Version 1.1.0
Rephrasing readme
Add cppo_V ocamlbuild flag.
