Specifics

Gargoyle is intended to care about typography, that is, to render the IF in a way most comfortable for reading. Features include specially chosen fonts, kerning, ligatures, text justification and many others. The options can be fine tuned in the simple text file 'garglk.ini'; for example, using Notepad on MS Windows, the text justification can be turned on by changing the line containing:

justify		0	# 0=ragged-right 1=justified

to

justify		1	# 0=ragged-right 1=justified
