1979# @DESCRIPTION:
1980# Check if the specified paths exist. Works for all types of paths
1981# (files/dirs/etc...). The -a and -o flags control the requirements
1982# of the paths. They correspond to "and" and "or" logic. So the -a
1983# flag means all the paths must exist while the -o flag means at least
1984# one of the paths must exist. The default behavior is "and". If no
1985# paths are specified, then the return value is "false".
