# Port config:
#    ALT_VER_EPOCH should be set to the first version that alt versioning
#      was enabled in. The port version matching ALT_VER_EPOCH will retain
#      PREFIX=LOCALBASE. Other versions will get PREFIX=ALT_PREFIX.
#    ALT_FILES should be set to a tuple of "file altfile" lists. For example:
#      ALT_FILES+= bin/vim           bin/vim${ALT_VER}
#      ALT_FILES+= man/man1/vim.1.gz man/man1/vim${ALT_VER}.1.gz
#      This will create symlinks from LOCALBASE/bin/vim${ALT_VER} and
#      LOCALBASE/man/man1/vim${ALT_VER}.1.gz to the real files in ALT_PREFIX.

# Default to PORTVERSION with removed '.' as the PKGNAMESUFFIX and ALT_VER
# comparison.

# ALT_VER_PORTVERSION_REG should convert the PORTVERSION and DEFAULT_VERSION
# value into the desired ALT_VER.
# The default will convert PORTVERSION=1.4.4 to 14.
