Put your *.fastq file to data directory
and use compress.py script to split and squeeze it:

  $ mv /tmp/ERR001268.filt.fastq ../data/
  $ python compress.py ../data/ERR001268.filt.fastq

All temporary files will be created in ../data/ 
One can use "test.py" script for automated testing.
For this write file "test.lst" like here

  ## Filename                       Quick flag                        cond_huffman
  ../data/tmp2.tmp                  True                              True 
  ../data/tmp2.tmp                  True                              False
  ../data/tmp.tmp                   True                              False  
  ../data/ERR001268.filt.fastq      False                             True 

and run "test.py" for testing or "test.py -q" for quick testing.
