DESCRIPTION="WPS Office is an office productivity suite, Here is the Chinese version"
HOMEPAGE="https://www.wps.cn/product/wpslinux/"

# WPS only publishes the .deb behind a CDN that requires a time-signed URL
# (t=unix-ts, k=md5(secret+path+t), valid for ~1h), so it cannot be expressed
# as a static SRC_URI. The community mirror used previously (dogfood.gnupg.uk)
# is stale for this release (its redirect points at a CDN object that no
# longer exists), so src_unpack() signs and fetches the URL itself.
MY_BUILD_ID="765474" # WPS build id, matches the current AUR wps-office-cn package
MY_SIGN_KEY="7f8faaaa468174dc1c9cd62e5f218a5b" # public CDN signing key (see the AUR PKGBUILD)
