# 20231229 ALe: Upgrade to Lazarus 3.0
# - moved fpc-source to fpc package (with new option for the user to exclude it).
# - added option to build lazarus with qt5 instead of gtk2.
# - commented lhelp link correction as sbopkglint does not complain anymore.

# 20220414 bkw: BUILD=2
# - fix PRINT_PACKAGE_NAME when ARCH not set in environment.
# - add gtk-update-icon-cache to doinst.sh.
# - remove empty files from doc dir.
# - fix broken symlink.

# 20210905 bkw:
# - take over maintenance
# - update for v2.0.12
# - get rid of fpc-source dep; include the source in this package
