# Summary: Detect the file that sets the current rbenv version
|
|
#
|
|
# Detects and prints the location of a `.ruby-version` file that sets the

|
# version for the current working directory. If no file found, this prints
|
|
# the location of the global version file, even if that file does
|
|
# not exist.
