11 usage: test-tool parse-options <options>
13 A helper function for the parse-options API.
16 -D, --no-doubt begins with 'no-'
17 -B, --no-fear be brave
18 -b, --boolean increment by one
19 -4, --or4 bitwise-or boolean with ...0100
20 --neg-or4 same as --no-or4
22 -i, --integer <n> get a integer
23 -j <n> get a integer, too
24 -m, --magnitude <n> get a magnitude
25 --set23 set integer to 23
26 -L, --length <str> get length of <str>
27 -F, --file <file> set file to <file>
32 --string2 <str> get another string
33 --st <st> get another string (pervert ordering)
34 -o <str> get another string
35 --list <str> add str to list
39 -NUM set integer to NUM
41 --ambiguous positive ambiguity
42 --no-ambiguous negative ambiguity
45 --abbrev[=<n>] use <n> digits to display SHA-1s
46 -v, --verbose be verbose
49 --expect <string> expected output in the variable dump
