 +===== Some infos =====
 +
 +Besides a nice prompt and some sane defaults this bashrc defines some handy utils as well:
 +
 +Convert DOS CRLFs to Unix LFs and vice versa:
 +
 +  $> dos2unix <files>
 +  $> unix2dos <files>
 +
 +Strip UTF-8 byte order marks
 +
 +  $> bomstrip <files>
 +
 +Change into a temp directory named after the todays date (create if nessary):
 +
 +  $> td
 +
 +Change into yesterday's temp dir:
 +
 +  $> td -1
