module Optimus
class Reader
# This class is for reading tab-delimited Optimus files. (Or, really, any tab-delimited file).
# The main option of interest is the :skip_lines option, which specifies how many lines
# to skip before finding column names. For example:
#
# TabfileParser.new(stream, :skip_lines => 1)
#
# is what you'd use for skipping the filename line in a standard optimus Excel file.
#
# Note: you'll generally be using subclasses of this, and not manually specifying skip_lines.
