Create a newMail where f is either a stream which
responds to gets(), or a path to a file. If f is a path it will be
opened.
The whole message is read so it can be made available through the #header,
#[] and #body
methods.
The "From " line is ignored if the mail is in mbox format.
# File lib/mailread.rb, line 12
def initialize(f)
unless defined? f.gets
f = open(f, "r")
opened = true
end
@header = {}
@body = []
begin
while line = f.gets()
line.chop!
next if /^From /=~line # skip From-line
break if /^$/=~line # end of header
if /^(\S+?):\s*(.*)/=~line
(attr = $1).capitalize!
@header[attr] = $2
elsif attr
line.sub!(/^\s*/, '')
@header[attr] += "\n" + line
end
end

f.close if opened
