 # Tag storms are one way of overcoming this challenge: they are easy for computers to parse, reduce the redundancy of a tab-separated file, and they are easily human readable. However, in other aspects of our work we are still largely stuck with text files organized into rows and columns.
 #
 # We stare at these files all day, so visually organizing them for a quick look has been a huge time saver for me (and prevented a lot of simple mistakes). Without tools like this, we'd have to perform a tedious series of cut commands or traverse our screen doing a lot of counting of columns, trying to figure out how blocks of text map. 
 #
 # This program allows you to view data as a grid, and allows you to define which delimiter you'd like to use (tab is used by default).

 #################################################################################
 # I want to truncate columns, probably using something like sed 's/\(.\{1,50\}\).*/\1/' this way there's no wrapping around the terminal (in which case, columns is a better program)
+# Some users of older shells report issues. Detect if user is running bash/zsh, otherwise exit.
