# Implements the logic behind the rake tasks for annotations like
#
# rake notes
# rake notes:optimize
#
# and friends. See <tt>rake -T notes</tt> and <tt>railties/lib/tasks/annotations.rake</tt>.
#
# Annotation objects are triplets <tt>:line</tt>, <tt>:tag</tt>, <tt>:text</tt> that
# represent the line where the annotation lives, its tag, and its text. Note
# the filename is not stored.
#
# Annotations are looked for in comments and modulus whitespace they have to
# start with the tag optionally followed by a colon. Everything up to the end
# of the line (or closing ERB comment tag) is considered to be their text.

end
# Returns a representation of the annotation that looks like this:
#
# [126] [TODO] This algorithm is simple and clearly correct, make it faster.
#
# If +options+ has a flag <tt>:tag</tt> the tag is shown as in the example above.
# Otherwise the string contains just line and text.

# +script+, and +test+ (recursively). Only filenames with extension
# +.builder+, +.rb+, +.erb+, +.haml+, +.slim+, +.css+, +.scss+, +.js+, and
# +.coffee+ are taken into account. The +options+ hash is passed to each
# annotation's +to_s+.
