go-envdir sets various environment variables as specified by files in the directory  named 
"/env/dir". It then runs "command".

If "/env/dir" contains a file named s whose first line is t, envdir removes an environment 
variable named s if one exists, and then adds an environment variable named s with  
value t. The name  s  must  not  contain =. Spaces and tabs at the end of t are removed.
Nulls in t are changed to newlines in the environment variable.

If the file s is completely empty (0 bytes long), envdir removes an  environment  variable
named s if one exists, without adding a new variable.`)
