Overview
This module reexports a slightly different version of the standard API which makes it more convenient for chaining monadically. Everywhere a ConfigParser was the first argument in a function in the standard API, it is now the last. This lets you rewrite
do let cp = emptyCP cp <- add_section cp "sect1" cp <- set cp "sect1" "opt1" "foo" cp <- set cp "sect1" "opt2" "bar" options cp "sect1"
as
return emptyCP >>= add_section "sect1" >>= set "sect1" "opt1" "foo" >>= set "sect1" "opt2" "bar" >>= options "sect1"
which may be more elegant in some cases. A future development might be to chain the ConfigParser implicitly with a state monad, which would be yet more elegant.
