Beware reserved ENV names in RailsNot all environment variable names are created equal.
For example, if you are using Ruby on Rails, do not declare a
VERSIONenvironment variable, there is already one a reserved. The reserved
VERSIONenvar is used by Rails in migrating database changes, so if it is changed at all, you will have problems when making new migrations.
That was a fun error to debug...
