Greg,
Thanks for the link. I examined its description. I actually have much more modest goals to simply adjust text format content and not upgrade it to HTML or any other richer format. I just want to get a better screen use for smaller reader screens.
For instance, I want to remove the annoying end-of-line markers that breakup paragraph into many segments and cause my reader to waste a lot of space:
After the line markers are removed:
Now the screen is filled and used very well, hence less scrolling.
I'll check the requirements list from the initial post and try to add more options. I'll post it as a freeware in a new post.

I use Java which has regular expressions capability. I plan to simply build some search/replace regexp patterns and allow a user to enter his/her own to customize according to individual preferences. Shouldn't be too bad. Actually most of the work is for interfaces, GUI and CLI.
