Caldera license question
I came across a "variant" of the Caldera license. Here is what we have on SPDX: https://spdx.org/licenses/Caldera.html
But this project - http://heirloom.sourceforge.net/sh.html has this license but it omits the first paragraph and next few lines. That part alone isn't a full match otherwise. (see attached)
I'm wondering if we should made that first part optional as it does seem to be very specific code, as listed.
The Heirloom Bourne Shell project is used in Fedora, so that's how it came up. I don't know if it's used elsewhere or if this variant of the license, but any info on that would be helpful!
