# Provide a minimalist realpath implementation to help deal with platforms that may not provide it
|
|
# as a command. If an external realpath or grealpath command is available simply pass all arguments
|
|
# thru to it. If not fallback to our builtin.
|
|
|
|
# The following is slightly subtle. We have to define a realpath function even if there is an
|
|
# external command by that name. That's because if we don't the parser will select our builtin.
|
|
# However, we only want our builtin if there is no external realpath command.
