v2.8.0

=====================================================================

--- Changes ------------------------------

- python library functions moved to `py/lib`
- python scwrypts renamed in kebob-case to help prevent import
- __name__ == '__main__' enforced on all python scwrypts

--- New Features -------------------------

- `__override` variables now allow values to be force-overwritten
- py.lib.http.client provides a slim `requests.request` wrapper

--- New Scripts --------------------------

py/data/convert )
  quick data converters
   - csv-to-json
   - csv-to-yaml
   - json-to-csv
   - json-to-yaml
   - yaml-to-csv
   - yaml-to-json

py/linear )
  uses the linear.app graphql API for PM tasks
   - comment

--- Bug Fixes ----------------------------

- `scwrypts` handles arguments with quotes and special characters

 Set environment variable `CI=true` (and use the no install method) to run in an automated pipeline.
 There are a few notable changes to this runtime:
 - **The Scwrypts sandbox environment will not load.** All variables will be read from context.
-	- The underscore-prefixed `_AWS_(PROFILE|REGION|ACCOUNT)` variables will be read from the standard `AWS_` variables
 - User yes/no prompts will **always be YES**
 - Other user input will default to an empty string
 - Logs will not be captured

 Nested children will inherit values from all parents.
 
+### Special Environment Variable Syntax
+
+All environment variables which end in `__[a-z_]+` are ignored by the template file.
+These environment variables *will propagate to children*, but will not be removed nor staged into the `.env.template`.
+
+#### `__select` Environment Variables
+Omit any variable, but provide a comma-separated list with the `__select` suffix, and the user will be prompted to select a value from the provided options.
+
+In the following configuration, the user will be prompted to select an `AWS_REGION` once at the beginning of scwrypt execution:
+
+```zsh
+export AWS_REGION=
+export AWS_REGION__select=us-east-1,us-east-2,us-west-1,us-west-2
+```
+
+Setting the `AWS_REGION` variable will cause scwrypts to ignore the `__select` syntax.
+
+CI will fail on select, because CI fails on any FZF prompt.
+
+#### `__override` Environment Variables
+Override any variable with the indicated value.
+This will take precedence over existing values *and* any other special environment variable types.
+
+Examples of use:
+- temporarily changing a single value in your current session (e.g. `export VARIABLE__override=value`)
+- overriding a variable for a one-time command (e.g. `VARIABLE__override=value scwrypts ...`)
+
+
