class File
# File.yaml? provides a way to check if a file is a YAML
# formatted file:
#
# File.yaml?('project.yaml') #=> true
# File.yaml?('project.xml') #=> false
#
# Note this isn't perfect. At present it depends on the use
# use of an initial document separator (eg. '---'). With
# YAML 1.1 the %YAML delaration is supposed to be manditory,
# so in the future this can be adapted to fit that standard.
