I did a comparison of the 3 parsers with the various option formats I had in
mind. Here are the results :
|| ||GNU||Posix||Basic||
||Flags\\(tar -xvf foo.tar)|(x)\\x is recognized|(/)|(x)\\ParseException|
||Long name with hyphens + space\\(--user ebourg)|(/)|(/)|(/)|
||Long name with hyphens + equal\\(--user=ebourg)|(/)|(/)|(x)\\ParseException|
||Short name with hyphen + space\\(-u ebourg)|(/)|(/)|(/)|
||Short name with hyphen + equal\\(-u=ebourg)|(/)|(x)\\value is
'=ebourg'|(x)\\ParseException|
||1 digit short name + value\\(-O1, -V3)|(/)|(/)|(x)\\ParseException|
||2+ digits short name +
value\\(-Xmx512M)|(x)\\ParseException|(x)\\ParseException|(x)\\ParseException|
