# Maintainer: Vladimir Panteleev <arch-pkg at thecybershadow.net>

# Note: this PKGBUILD is a little more complicated than it could be,
# because we try to be strictly pedantic about separating the download
# phase from the build phase to conform to PKGBUILD ideals.
#
# Namely, all PKGBUILDs should ideally be written such that:
#
# - The download phase is done by the package build tool
#   (i.e. everything and anything that needs to be obtained from the
#   Internet is listed in the source array).
#
# - The download phase does not run any external code.
#
# - The build phase does not access the Internet.
#
# Satisfying these constraints allows users to configure the download
# mechanisms to e.g. use proxies and provides security and
# reproducibility guarantees.
#
# If you are packaging btdu and don't care about the above, you can
# skip all the "dub add-local ..." commands and simply run "dub build
# -b release", as documented in btdu's README.
