+FreeType View - display the bitmap representation of a FreeType font file.
 
-Examples:
-  python3 ft-view.py ttf-fonts/Vera.ttf 13           --> Will displays all the characters
-  python3 ft-view.py ttf-fonts/Vera.ttf 13 --char=A  --> Display only the char "A"
-  python3 ft-view.py tft-fonts/heydings_icons.ttf 23 --char=A --descenders=   --> ignore all descenders
-  python3  ft-view.py ttf-fonts/Vera.ttf 13 --descenders=p,q,j,#34 --> change the descenders
-  python3  ft-view.py ttf-fonts/Vera.ttf 13 --descenders=          --> No descenders so baseline = bottomline! 
-  python3  ft-view.py ttf-fonts/Vera.ttf 13 --special-align=a:T,=:B,#126:M --> change the special alignment instruction. a on TOP, = on Bottom, ~(#126) in middle (between the baseline and top)
-  python3  ft-view.py ttf-fonts/Vera.ttf 13 --special-align=       --> delete special alignments. All chars on Bottom line (ideal for Wingdings chars).
+This script is useful for obtaining font sizing (in pixels) and its bitmap representation.
