This is a little something I created for my own use. A small CLI tool that lets you split completions into snippets,. or merge multiple snippet files into one completion file. I wrote about the pros & cons of either format here.
# Converts snippets into completions, use quotes with wildcards
$ glue "*.sublime-snippets" > result.sublime-completions
# Converts completions into a snippets
$ scissors result.sublime-completions --output Snippets
