#
# Debian package build for PostIt (Yavsc desktop client).
#
# Pipeline:
#   1. Clone pazof/yavsc at POSTIT_GIT_TAG into a clean working
#      tree under $(BUILDDIR)/yavsc-src.
#   2. Restore + publish src/PostIt/PostIt.Desktop as a
#      linux-x64, framework-dependent (not self-contained)
#      assembly tree into $(BUILDDIR)/postit-app.
#   3. Render the icon at the hicolor sizes (16, 32, 48,
#      64, 128, 256) from src/PostIt/PostIt/Assets/Icon.png,
#      plus the SVG from the same directory as the scalable
#      form.
#   4. Lay out the package tree:
#         /usr/lib/postit/           (managed assemblies)
#         /usr/bin/postit            (wrapper script)
#         /usr/share/applications/   (postit.desktop)
#         /usr/share/icons/hicolor/  (icons)
#   5. Run dh to install, fix permissions, build the binary
#      package.
#
# Override POSTIT_GIT_TAG or POSTIT_GIT_URL on the make command
# line to build a different upstream revision:
#
#   make deb POSTIT_GIT_TAG=1.0.1
#   make deb POSTIT_GIT_URL=https://github.com/fork/yavsc.git
