bash/release.sh

# This bash file is intended to be used for building .deb release
# files to be used by pull and push. To use this file just
# create your own bash file in which you define the APPNAME and DESCRIPTION
# vars and the copy_release_files() function which copies all the files
# needed in the distribution in ${ROOT}. Then source this file
# after those definitions. The resulting .deb will be uploaded to Google
# Storage with the correct metadata.
#
# Follow Debian conventions for file locations. For example:
#
# HTML Template files in /usr/local/share/${APPNAME}/.
# Binaries in /usr/local/bin/${APPNAME}.
# Small read/write files in /var/local/${APPNAME}/.
# Config files in /etc/${APPNAME}/.
#
# The first command line argument to the calling script
# will be used as the 'note' for the release package.
#
# For more details see ../push/DESIGN.md.
