Usage: $0 <expected-hint-file> <actual-hint-file>
|
|
|
|
Print differences between the hint information in the two files. The files
|
|
must in a CSV format delimited by '|'. The easiest way to obtain such a
|
|
file is to use hintextract.
|
|
|
|
The output is sorted lexigraphically in reverse order. If the arguments
|
|
are reversed, the new output can also be generated from the old one by
|
|
reversing the signs and sorting again in reverse order (under LC_ALL=C).
|
|
It only works with uncolored output.
|
|
|
|
Returns with a zero exit code under normal conditions, even when the hints
|
|
do not match.
