# 8. Paragraph filling: formatting text

The package GNATCOLL.Paragraph_Filling provides several algorithms for filling paragraphs—formatting them to take up the minimal number of lines and to look better. Knuth_Fill is based on an algorithm invented by Donald Knuth, and used in TeX. Pretty_Fill uses a different algorithm, which was judged by some to produce more aesthetically pleasing output.

More detailed documentation may be found in the comments in the package spec.
