dsemver lets the computer compute the SemVer of your dlang software.

run

'''
$ ./dsemver -- -p PATH_TO_PROJECT -l
'''

To compute the public interface of your latest git tag that looked it a SemVer
than you can run

'''
$ ./dsemver -- -p PATH_TO_PROJECT -c
'''

To compute the next SemVer of your project.`);
