this is the binktrim program in ruby. i'm not happy with it. this took me
WAY longer to write than the perl version. ruby's 'principle of least
suprise' turned out to be the 'principle of most suprise'

ruby does not have perl's magic. it could be that i was trying to write it
too perlish, but for a quick and dirty script i should have had to fiddle
with classes, etc.

the output isn't quite what i wanted (you'll see if you compare the perl
trimmed file to the ruby trimmed file.)

the only advantage i can see with the ruby version is the parse method for
Time. and the program is definitely slower.

i think for larger oo projects i would stick with itcl or ruby, probably
not perl, and definitely not python.

    td2.push(year)
    td3=td2.join(s=" ")
    t1=Time.parse(td3)
    t3 = t2 - 24 * 3600 * ARGV[1].to_i
    t.print("#{logline}") if t1>t3
 end
 t.print "#{line}" if line=~/^\s*$/
}
l.close
File::copy(t.path, ARGV[0])
t.close(true)
