# This library is part of sendmail, but it does not share the version number with it.
# In order to find the right libmilter version number, check SMFI_VERSION definition
# that can be found in ${S}/include/libmilter/mfapi.h (see also SM_LM_VRS_* defines).
# For example, version 1.0.1 has a SMFI_VERSION of 0x01000001.

# See check in src_prepare too.

# We used to use $(ver_cut 1-3) here (assuming ABI stability between sendmail
# versions) but that doesn't seem to apply for sendmail snapshots.
