chcpumf installed with s390-tools version 2.14.0 no longer provides version or help information

I found the root cause. When no CPU-measurement sampling facility is detected,
this error is printed first:

No CPU-measurement sampling facility detected

regardless of any command line options specified. Then program then exits.
This happened during the rewrite from perl to C.

When the CPU-measurement sampling facility is available and detected,
the command line options -h and -v are properly processed.

This error shows up only when no CPU-measurement sampling
facility is detected. Without any installed CPU-measurement sampling
facility, you can not change the CPU-measurement sampling facilities
buffer sizes (because it is not there!).

So I will change the code to honour previous behavior and print help
string and version number, even if the program can not be used properly.

Hello John, or anyone else affected,

Accepted s390-tools into groovy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/s390-tools/2.14.0-1ubuntu1.1 in a few hours, and then in the -proposed repository.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-groovy to verification-done-groovy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-groovy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

I can confirm that it works with package 2.14.0-1ubuntu1.1:
$ dpkg -l | grep s390-tools
ii s390-tools 2.14.0-1ubuntu1.1 s390x fundamental utilities for Linux on z Systems
ii s390-tools-signed 2.14.0-1ubuntu1.1 s390x Signed zipl stage3.bin

I get again proper version and help info - even if the sampling facility is not active:

$ chcpumf -v
CPU-measurement facility utilities, version 2.12.0-build-20200320
Copyright IBM Corp. 2014, 2017

$ chcpumf -h
Usage: chcpumf -h|-v
 chcpumf -m num_sdb
 chcpumf -x num_sdb

Options:
 -m num_sdb Specifies the initial size of the sampling buffer.
        A sample-data-block (SDB) consumes about 4 kilobytes.
 -x num_sdb Specifies the maximum size of the sampling buffer.
        A sample-data-block (SDB) consumes about 4 kilobytes.
 -h Displays help information, then exits.
 -v Displays version information, then exits.

For more help information, issue 'man chcpumf'.

Adjusting the tags accordingly ...
