"""ttroundtrip font1 ... fontN

Dump each font as TTX, compile again to TTF or OTF and dump again.
|
||
|
|
Then do a diff on the two TTX files. Log problems and diffs to a
|
||
|
|
file called "report.txt" in the current directory. This is only
|
||
|
|
for testing FontTools/TTX, the resulting files are deleted
