 .Synopsis
  The TinyORM library bumping version numbers and deployment script

 .Description
  The `deploy.ps1` script helps with bumping version numbers for all libraries and deploying these changes to the `main` branch. It also outputs all the available information and allows to confirm or cancel future processing.

  It does the following actions:

  - test the current working directory is correct
  - test if the main or develop branch are behind
  - test if the current branch is develop
  - test if the current working tree is clean
  - updating number of unit tests in all documentation files
    - obtain the current number of unit tests from the README.md file
    - verify the current number of unit tests in all files whether is the same everywhere
    - print the number of unit tests to the console
    - read the new number of unit tests to update in all files
    - verify the new number of unit tests
    - update the Number of Unit Tests in all files defined in the $Script:NumberOfUnitTestsLocations
    - display the diff summary and approve to continue
    - get the commit message for updated number of unit tests
    - commit
  - allow to skip bumping version numbers
  - ask which version numbers to bump for the `TinyOrm`, `tom`, `TinyDrivers`, `TinyMySql`, and `TinyUtils` projects
  - display bumped version numbers to verify them
  - display bumped tag number to verify it
  - update bumped version numbers in all `version.hpp` files and also in all other files
  - show diff summary
  - prepare the bump commit message with the bumped version numbers
  - commit the bump commit message
  - prepare a tag message with the bumped version number
  - create an annotated git tag
  - merge the `develop` to the `main` branch (ff-only), and push to the `origin/main`
  - update the vcpkg `tinyorm` portfile
    - obtain the `origin/main` commit ID (SHA-1) or use the tag number (based on select mode)
    - update the REF value
    - obtain the `origin/main` archive hash (SHA512)
    - update the SHA512 value
    - remove the port-version field from vcpkg.json files if TinyOrm version number was bumped
    - if TinyOrm version number wasn't bumped allow to bump the port-version number in vcpkg.json
  - prepare the vcpkg commit message
  - do the commit, merge to the `main` branch (ff-only), and push to the `origin/main`

  The deployment is not possible without bumping the `TinyOrm` library version number because a git tag must be created. That means that bumping only the `tom`, `TinyDrivers`, `TinyMySql`, or `TinyUtils` isn't possible. This used to be possible, but not anymore because git tags are created during deployment.

  There is a second mode that allows to completely skip bumping version numbers and in this case is possible to deploy the vcpkg ports only. The vcpkg ports will use the git commit ID of the main branch for the vcpkg_from_github REF option in this case. The first approval question allows you to select this so-called second mode.
