flaws that the code might cause

due to the fact that the professor wrote the trans file in non-standard, difficult to parse format the program would fail to recognize some complex Regexes such like /a-z/ 3 which will replace every letter with the number 3.

still to do

1. check for the safety of the files and paths.
