| .Synopsis | ||
| Leinengen bootstrap. | ||
| .Parameter Command | ||
| The command to pass to leiningen. | ||
| .Notes | ||
| This is a very literal port of lein.bat to PowerShell. | ||
| TODO: | ||
| - Determine which (if any) environment variables are used from within Leiningen/Clojure | ||
| and convert the rest to local- or script-scoped variables. | ||
| - Probably should parse the version from the newest .jar filename, rather than hard-code | ||
| it and search for the .jar file from it. | ||
| - Further reduce/simplify/refactor away from batch-file idioms toward idiomatic PowerShell. | ||
