# 20241019 bkw: update for v3.0.0d (in conjunction with Greg's pdfpc update).

# 20240807 bkw: note to self:
# - tried to update for v3.0.0d, but pdfpc fails to compile with it.
#   looked for a fix in pdfpc's git, but latest git fails with the
#   same error. so, not updating this build until there's a new
#   pdfpc release that can handle it.

# 20230914 bkw:
# - take over maintenance.
# - update for v2.2.7d.
# - don't install VERSION in doc dir.
# - add MAKETEST option, disabled by default, to run 'make test'.
