Write one

A recipe for software that has none. A port from conda-forge or Spack. A bump to the next generation. An easyblock when a parameter is not enough.

• Build your own, without asking anyone
• eb-stack ports a recipe and bumps one
• Writing one from nothing
• Writing an easyblock
• Extensions, and what an entry in exts_list inherits
• Inspect writes a work queue, not a recipe
• Format, lint, and check are three different questions
• A stack lock is not a package lock
• A campaign finding is a typed failure, not a log
• A wrapper is the range EasyBuild will not write
• Four EasyBuild 5 surfaces the earlier chapters skipped
