# A script to check jfrog (bintray) for binaries existence and update package file
#
# Usage
#
#   chkfrog package...              Check packages
#
# Directory structure
#
#   Unfortunately, we need to have sha256 files locally to update URL correctly.
#
#   release/armv7l/*.tar.xz.sha256  SHA256 files for armv7l
#   release/i686/*.tar.xz.sha256    SHA256 files for i686
#   release/x86_64/*.tar.xz.sha256  SHA256 files for x86_64
