Converting several observation reports to little_r

[MUWRFDA]

I have downloaded a Fortran program to convert a sounding obsertion to littel_r here ftp://ftp.ucar.edu/mesouser/MM5V3/V3-7-0/LITTLE_R.TAR.gz. This program is easily adaptible to converting a single surface observation to little_r. I would like to convert a whole bulletin of a long list of observation (a mixture of synop, metar and speci) into a single little_r formatted file. Adapting the above program will take me very long (perhaps a few months).
I will appreciate if there is anyone who may have a ready Fortran program (or Perl script) to accomplish the task, for a sample of data as below.

This work should be made by yourself because the original data formats others cannot get it.
What you should do is reading and reorganizing the data as the program need.
