# 20240908 bkw: update for v1.3.4_20240905.
# 20240813 bkw: update for v1.3.4_20240622.
# 20240315 bkw: update for v1.3.4_20240123.
# 20230822 bkw: Update for v1.3.4_20230808.
# Sorry this went so long without updates.
# - get MANIFEST out of the package doc dir (don't need).
# - install examples/ to the doc dir (but without +x perms).
# - run 'make check' by default, undocumented MAKECHECK=no to disable.
# - if 'make check' is run, save the results to the doc dir.
# - POSIX intervals (brace expressions) are now supported in the
#   built-in regex engine, so update README accordingly.
# 20200302 bkw: Update for v1.3.4_20200120.
# 20200111 bkw: Update for v1.3.4_20200106.
# 20191129 bkw: Update for v1.3.4_20190203.
# 20180902 bkw: Add BUILTIN_REGEX option.
