#! /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 main plugin file name.
#  5. Check main plugin file exists.
#  6. Check readme.txt version matches main plugin file version.
#  7. Ask for temporary SVN path.
#  8. Ask for remote SVN repo.
#  9. Ask for SVN username.
# 10. Ask if input is correct, and give chance to abort.
# 11. Check if Git tag exists for version number (must match exactly).
# 12. Checkout SVN repo.
# 13. Set to SVN ignore some GitHub-related files.
# 14. Export HEAD of master from git to the trunk of SVN.
# 15. Initialise and update and git submodules.
# 16. Move /trunk/assets up to /assets.
# 17. Move into /trunk, and SVN commit.
# 18. Move into /assets, and SVN commit.
# 19. Copy /trunk into /tags/{version}, and SVN commit.
# 20. Delete temporary local SVN checkout.
