| Prints to stdout a list of release numbers in ascending order | |

| • In all operating modes, the simple answer (if found) is printed to stdout; fancier explanatory | |

| • On eus channels: one could argue that modes 1 & 3 should check & treat "eus" channels as | |
| *higher* than "stable" ... rsaw is ambivalent about this. Feel free to contact him. | |
| • On prerelease channels: as of 2021-01, these were only used in 4.1 & 4.2, so are ignored. | |

Random update: I just started running this on a Fedora35 system which had a jq rpm installed, so I didn't need to download jq manually like I have in the past (from github.com/stedolan/jq/releases). However, I was horrified to find that jq's sorting wasn't working correctly. See:
That's with:
$ rpm -q jq
jq-1.6-10.fc35.x86_64
$ jq -V
jq-1.6
So I went and grabbed the binary direct from the latest (Nov 01, 2018) release on github and put that in my ~/bin/ and now all is well with jq's sorting:
So let this serve as a warning against using distro-provided packages. Sigh.
Pushed a minor cosmetic update that has no functional changes -- I only changed the usage/help pages to (hopefully) improve clarity, replacing all instances of OCP_VERSION with simply 4.x.y and replacing all instances of OCP_MAJOR_VERSION with 4.x. It's an improvement.

Massive update. This should really be in a repo, but oh well not today. New screenshots follow.
Three different operating modes, depending on what args you pass
(screenshot updated 2022-11-11; minor cosmetic change)
Mode 1: Determine highest channel in which 4.x.y can be found
(The original sole behavior -- prior to massive update.)
Verbosity is fun
Mode 2: Determine newest release of 4.x found in a channel
Verbosity
Mode 3: Determine available upgrade paths from starting 4.x.y to desired 4.x
Verbosity
Full help page
