v3.6.1
===================================================================== --- Changes ------------------------------ - Adjusted USAGE (from zsh/lib/utils/io.zsh) to allow dynamic variable insertion in help dialogues by setting USAGE__<help-group> and using the syntax listed - Various quality-of-life changes and and fixes to experimental kubectl plugin --- Bug fixes ---------------------------- - sourcing 'scwrypts.plugin.zsh' no longer sets __SCWRYPT=1 in your current environment

Provides 'k' (kubectl) and 'h' (helm) shorthands to the respective

allow quick selection of contexts and namespaces usable across all

active shell instances.

The scwrypts group 'kubectl' has simple selection executables for

kubecontext and namespace, but also provides the library to enable

enriched, use-case-sensitive setup of kubernetes context.
