# gen-docs generates a new versioned docs directory under site/docs. It follows
# the following process:
#   1. Copies the contents of the most recently tagged docs directory into the new
#      directory, to establish a useful baseline to diff against.
#   2. Adds all copied content from step 1 to git's staging area via 'git add'.
#   3. Replaces the contents of the new docs directory with the contents of the
#      'master' docs directory, updating any version-specific links (e.g. to a
#      specific branch of the GitHub repository) to use the new version
#   4. Copies the previous version's ToC file and runs 'git add' to establish
#      a useful baseline to diff against.
#   5. Replaces the content of the new ToC file with the master ToC.
#   6. Update site/_config.yml and site/_data/toc-mapping.yml to include entries
#      for the new version.
#
# The unstaged changes in the working directory can now easily be diff'ed against the
# staged changes using 'git diff' to review all docs changes made since the previous 
# tagged version. Once the unstaged changes are ready, they can be added to the
# staging area using 'git add' and then committed.
#
# To run gen-docs: "NEW_DOCS_VERSION=v1.1.0 make gen-docs"
#
# **NOTE**: there are additional manual steps required to finalize the process of generating
# a new versioned docs site. The full process is documented in site/README-JEKYLL.md.
