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 --mode1 set integer to 1 (cmdmode option)
27 --mode2 set integer to 2 (cmdmode option)
28 -L, --length <str> get length of <str>
29 -F, --file <file> set file to <file>
34 --string2 <str> get another string
35 --st <st> get another string (pervert ordering)
36 -o <str> get another string
37 --list <str> add str to list
41 -NUM set integer to NUM
43 --ambiguous positive ambiguity
44 --no-ambiguous negative ambiguity
47 --abbrev[=<n>] use <n> digits to display SHA-1s
48 -v, --verbose be verbose
51 --expect <string> expected output in the variable dump
54 -A, --alias-source <string>
56 -Z, --alias-target <string>
57 alias of --alias-source
