creates the database maps used by the keyed map lookups in
sendmail 8 .
It reads input from the standard input
and outputs them to the indicated
mapname .
Depending on how it is compiled,
handles up to three different database formats,
selected using the
maptype
parameter.
They may be
-tag -width Fl
Li btree
B-Tree format maps.
This requires the new Berkeley DB
library.
Li hash
Hash format maps.
This also requires the Berkeley DB
library.
In all cases,
reads lines from the standard input consisting of two
words separated by white space.
The first is the database key,
the second is the value.
The value may contain
``%n''
strings to indicated parameter substitution.
Literal percents should be doubled
(``%%'').
Blank lines and lines beginning with ``#'' are ignored.
-tag -width Fl
Fl N
Include the null byte that terminates strings
in the map.
This must match the -N flag in the sendmail.cf
``K'' line.
\nP \
\{\
Fl c
Use the specified hash and B-Tree cache size.
