Status of project

首先审查 hpp-skel 现有的 CLI 示例、mapbox/cpp#35 中尚未解决的 option-parser 讨论，以及提议的 cpp-cli-skel#2 pull request。确定该项目应该暂停还是重新启动；完成的标准是维护者已经选择并记录了明确的方向。

I see great value to cpp-cli-skel because:

• Command line interfaces are a great way to prototype new projects
• Command line interfaces are a common and very valuable way to distribute C++ code, and therefore establishing best practices for how Mapbox devs develop C++ CLI interfaces is important for scaling our work.

At the same time this project has been dormant, in my mind, because:

• Attention of @mapbox/core-tech has so far been primarily on https://github.com/mapbox/hpp-skel
• https://github.com/mapbox/hpp-skel, because it contains benchmarks and unit tests executables, already has two types of "cli" examples, and therefore is fairly useful for using to prototype (no need for this separate cpp-cli-skel)
• Most serious command line tools end up needing to parse options, and option parsing in C++ requires an external dependency, which raises the harder question of which external dependency, refs https://github.com/mapbox/cpp/issues/35

Questions in my mind:

• Should we put this project on ICE and clearly direct interested people to hpp-skel for prototyping for now?
• Should we put time into investigating the ideal option parser and reboot https://github.com/mapbox/cpp-cli-skel/pull/2 with it and get things landed and working?
