#
# == Synopsis
#
# URI::Parser.new([opts])
#
# == Args
#
# The constructor accepts a hash as options for parser.
# Keys of options are pattern names of URI components
# and values of options are pattern strings.
# The constructor generates set of regexps for parsing URIs.
#
# You can use the following keys:
#
# * :ESCAPED (URI::PATTERN::ESCAPED in default)
# * :UNRESERVED (URI::PATTERN::UNRESERVED in default)
# * :DOMLABEL (URI::PATTERN::DOMLABEL in default)
# * :TOPLABEL (URI::PATTERN::TOPLABEL in default)
# * :HOSTNAME (URI::PATTERN::HOSTNAME in default)
#
# == Examples
#
# p = URI::Parser.new(:ESCAPED => "(?:%[a-fA-F0-9]{2}|%u[a-fA-F0-9]{4})")
# u = p.parse("http://example.jp/%uABCD") #=> #<URI::HTTP:0xb78cf4f8 URL:http://example.jp/%uABCD>
# URI.parse(u.to_s) #=> raises URI::InvalidURIError
#
# s = "http://example.com/ABCD"
# u1 = p.parse(s) #=> #<URI::HTTP:0xb78c3220 URL:http://example.com/ABCD>
# u2 = URI.parse(s) #=> #<URI::HTTP:0xb78b6d54 URL:http://example.com/ABCD>
# u1 == u2 #=> true
# u1.eql?(u2) #=> false
