See the libdwarf-code/codingstyle file in the libdwarf distribution.
There is no configure here, just a single simple Makefile.
# to build:
make
# to check it is built properly:
make check
Usage: dickeck [-l] file ...
dicheck checks for certain violations of the libdwarf codingstyle (see the libdwarf-code/codingstyle file in the libdwarf distribution)
Add -l to the command and dicheck also reports all lines longer than 70 characters (an arbitrary limit).
Usage: trimtrailing <file.c>
trimtrailing removes all trailing whitespace from file.c. Multiple blank lines in a row are reduced to a single blank line. It writes the changed file into <file.c>
