 # TODO

-## Systemic Issues
- - how do we integrate mongoc's error handling with c++'s error handling facilities
- - how do we integrate mongoc's memory management with c++'s memory management facilities
- - header include discipline (eg. do we put package prefixes?)
- - remove type tags on closing braces?
- - inlining pass for trivial methods / free functions
- - noexcept pass where possible
-
-## Build
- - `find_libmongocxx` cmake helper thing
- - figure out how to generate pc files (package config)
- - understand libc++ inline macros and determine if we need to use them
- - inline visibility macros -- do we want/need? how do we define them?
- - template visibility macros? -- do we want/need? how do we define them?
- - think about the relationship between include directory and package config
-
-## Organization
- - do we need a namespace for base or should we move its contents up a level
-
-## Docs
- - add a cmake target for this
