+ PYTHON Name of python command to use in

Additionally, various options can be specified on the configure
command line.

--zshcompletiondir=DIR Zsh completions files [PREFIX/share/zsh/functions/Completion/Unix]
-Some specific library versions can be specified (auto-detected otherwise):
-
- --with-gmime-version=VERS Specify GMIME version (2.4 or 2.6)
-
Some features can be disabled (--with-feature=no is equivalent to
--without-feature) :
- --without-emacs Do not install lisp file
--without-bash-completion Do not install bash completions files
+ --without-docs Do not install documentation
+ --without-api-docs Do not install API man page
+ --without-emacs Do not install lisp file
+ --without-ruby Do not install ruby bindings
--without-zsh-completion Do not install zsh completions files
+ --without-retry-lock Do not use blocking xapian opens, even if available

configure-script calling conventions, but don't do anything yet:
