I was glancing at one of the most popular scripts at the REBOL archive and developed
some questions:
1- Is it possible to incrementally write to a file in REBOL?
2- Is it possible to append to a file in REBOL
3- This script seems in-efficient and memory wasteful: it reads and entire file into a
temporary array and then converts the array. In Perl, I could do each conversion as I
read in each line and write each line out after each conversion.
