%description
%executable extracts and processes warnings from build logs so that
two logs can be compared (by diff) to detect whether new warnings appeared.

Now it simply deletes line numbers from compiler warnings (because they might
differ after the source code changed.) It is suited to the format of warnings
produced by gcc or lcc.

Usage: %executable [--rpmb (p|c|i|STAGE)]

Usage example:

diff -d <(%executable --rpmb c <hsh.log.0 |sort) <(%executable --rpmb c <hsh.log.1 |sort)

%prep
%setup -T -b 1 -n %name-%version-tests
# In the testdata, the next lines after this warning have different numbers
# translated/untranslated messages, therefore we delete them
# to ignore these differences in our tests.
sed -re "/warning: header field 'Language' still has the initial default value/ d" \
   -i */hsh.log.*

%install
install -pm0755 -D %SOURCE0 -T %buildroot%_bindir/%executable
