v1.0.1

Changes:

• Fixed error where mupdf was unable to open a pdf created with -T pdf flag. This was caused by removing the ampersand at the end of the groff execute line. This ampersand was extraneous (as groff does not need to run in the background) and was apparently problematic to mupdf reading the pdf created this way.
• Corrected typo in licence in source code.
