#About the code: This code combines many ruby files into one document, does some formatting (such as: prints each file name, removing whitespace at bottom of each file), it either removes or keeps comments. Then uploads to your github account as a public gist. Also a file called combined.rb is created in the folder that is same file uploaded to gist.  The public gist is opened in your web browser.  Installation of the gist gem is necessary using command: $ gem install gist

#About the input.txt file: This code uses an input file input.txt in the same directory, with first line containing the gist name, 2nd line whether or not you want comments, and the rest of the lines are the paths of the ruby files you want to combine relative to the location of this code (or just write out the entire path)

######sample input.txt file#######
#gist_name: homework_solutions
#keep_comments: false
#learn_ruby/00_hello/hello.rb
