* TODO [2014-12-19 Jum] shcompgen: add support for Getopt::Alt, Getopt::complete [#E]

  these are modules which i don't write. let's see first how many are their
  reverse deps?

* TODO [2015-01-04 Min] shcompgen: add support for Getopt::Long::Descriptive

  this module uses Getopt::Long as the backend, so we just need to detect its
  usage and then use Getopt::Long::Dump as usual. example scripts that use
  Getopt::Long::Descriptive: cpan-upload, ...

* TODO [2014-12-26 Fri] shcompgen: support glsubc
* TODO [2014-12-16 Tue] dzp-ri-absfmeta, pwp-ri, shcompgen, app-genbashcompleter: recognize NO_PERICMD_SCRIPT tag
* IDEA [2014-12-13 Sat] shcompgen: allow listing (and removing?) completion scripts not generated by us

  yang amannya sih list doang, misalnya: list --all.

* TODO [2014-12-13 Sat] shcompgen: jangan support dulu jika subcommands dynamic (coderef)
* TODO [2014-12-13 Sat] shcompgen: support fish dan zsh

  - kode dari peris2fishcomp & pericmdutil-fishcomp harus digabung
