Is there a tool or service for making this easy? So far, I've found fpm[1]. I haven't dug into it enough to know whether it's the solution I'm looking for, but I also wanted to solicit the community for alternatives in case I'm missing something even better.

The dependencies are minimal (just Ruby stdlib). Here are options I've considered and opted against:

• rubygems: I'm not a huge fan of using a language's package manager for end-user software. What happens when the system upgrades its version of Ruby? Does the user have a ruby version manager like rvm or rbenv installed? and so on.

• docker: a couple weeks back, an article entitled "Run More Stuff in Docker" was trending here[2]. I like the idea, but the approach is a minor hobby unto itself and way too burdensome to ask of general-audience, potentially not-very-technical end-users.

My program is simple enough that I hope it could be used as an introduction to CLI concepts/UNIX/shell pipes for the uninitiated; someone should not have to be a developer to use it or understand how it works. Assuming a very limited familiarity with the command line, I want to offer install instructions that make no assumptions about the user's system and should always just work; e.g., `brew install cram` / `sudo dpkg -i cram.deb` / etc.
