11 usage: test-parse-options <options>
14 -D, --no-doubt begins with 'no-'
15 -B, --no-fear be brave
16 -b, --boolean increment by one
17 -4, --or4 bitwise-or boolean with ...0100
18 --neg-or4 same as --no-or4
20 -i, --integer <n> get a integer
21 -j <n> get a integer, too
22 -m, --magnitude <n> get a magnitude
23 --set23 set integer to 23
24 -t <time> get timestamp of <time>
25 -L, --length <str> get length of <str>
26 -F, --file <file> set file to <file>
31 --string2 <str> get another string
32 --st <st> get another string (pervert ordering)
33 -o <str> get another string
34 --list <str> add str to list
38 -NUM set integer to NUM
40 --ambiguous positive ambiguity
41 --no-ambiguous negative ambiguity
44 --abbrev[=<n>] use <n> digits to display SHA-1s
45 -v, --verbose be verbose
48 --expect <string> expected output in the variable dump
