README for prt-utils version 1.3.2 offers the user-facing part of prtverify in two alternative implementations: bash and gawk. The `make install` rule creates /usr/bin/prtverify pointing to the gawk version. Feel free to change the target of the symlink, define an alias in your profile (e.g., alias prtverify="/usr/bin/prtverify.sh "), or put a different prtverify earlier in $PATH, if you prefer a more traditional wrapper for the awk tests.
