dnssec-dsfromkey incorrectly reports "file not found" if it is given a
filename that doesn't end in .key:

$ dig +noall +answer dnskey . >root-dnskey
$ dnssec-dsfromkey root-dnskey >root-ds
dnssec-dsfromkey: fatal: invalid keyfile name root-dnskey: file not found
$ mv root-dnskey root-dnskey.key
$ dnssec-dsfromkey root-dnskey.key >root-ds
$ dnssec-dsfromkey -?
Usage:
    dnssec-dsfromkey options [-K dir] keyfile

    dnssec-dsfromkey options [-K dir] [-c class] -s dnsname

    dnssec-dsfromkey options -f zonefile (as zone name)

    dnssec-dsfromkey options -f zonefile zonename

Version: 9.7.1-P2
Options:
    -v <verbose level>
    -K <directory>: directory in which to find key file or keyset file
    -a algorithm: digest algorithm (SHA-1 or SHA-256)
    -1: use SHA-1
    -2: use SHA-256
    -l: add lookaside zone and print DLV records
    -s: read keyset from keyset-<dnsname> file
    -c class: rdata class for DS set (default: IN)
    -f file: read keyset from zone file
    -A: when used with -f, include all keys in DS set, not just KSKs
Output: DS or DLV RRs
