#! /bin/bash
# See https://github.com/GaryJones/wordpress-plugin-svn-deploy for instructions and credits.
#
# Steps to deploying:
#
#  1. Ask for plugin slug.
#  2. Ask for local plugin directory.
#  3. Check local plugin directory exists.
#  4. Ask for local SVN assets directory.
#  5. Check local SVN assets directory exists.
#  6. Ask for main plugin file name.
#  7. Check main plugin file exists.
#  8. Check readme.txt version matches main plugin file version.
#  9. Ask for temporary SVN path.
# 10. Ask for remote SVN repo.
# 11. Ask for SVN username.
# 12. Ask if input is correct, and give chance to abort.
# 13. Check if Git tag exists for version number (must match exactly).
# 14. Checkout SVN repo.
# 15. Set to SVN ignore some GitHub-related files.
# 16. Export HEAD of master from git to the trunk of SVN.
# 17. Initialise and update and git submodules.
# 18. Move /trunk/assets up to /assets.
# 19. Move into /trunk, and SVN commit.
# 20. Move into /assets, and SVN commit.
# 21. Copy /trunk into /tags/{version}, and SVN commit.
# 22. Delete temporary local SVN checkout.
