[stevieb]: As far as Dist::Zilla goes, I don't like installing that other than on systems my test platorm runs on. I find it too heavy. I prefer being able to glean a Makefile.PL
[LanX]: what's frustrating me is that a distribution has lots of dupplicated info
[stevieb]: LanX I don't know if it's dialog driven; I just use it in the simplest of terms (just run module-starter at the CLI, and the very last couple of lines are how I use it.
[stevieb]: which dist are you speaking of regarding dups, LanX?
[LanX]: readme version number and so on ...
[stevieb]: with M::S, you can also add other tags, but defaults work... such as --license=perl --eumm
[LanX]: I'm not a big fan of pure make, apparently the auto generated ones are so complicated to be able to work with all possible makes
[stevieb]: I find the M::S makefiles it generates are quite straight forward, and I usually have to add a few things (github info etc). They're about 15 lines or so give or take.
[Corion]: I don't think the EUMM-generated Makefile is that complicated ;)
