makemap creates the database maps used by the keyed
map lookups in sendmail(1M). makemap reads from the standard input and outputs to the specified mapname.
In all cases, makemap reads lines from the standard
input consisting of two words separated by whitespace. 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.
makemap handles three different database formats.
Database format is selected using the maptype
parameter. See OPERANDS.
The following options are supported:
Use the specified hash and B-Tree cache size (cachesize).
Use the specified sendmail configuration file (file) for looking up the TrustedUser option.

keys are read, both be inserted into the map.
Use the specified character to indicate a comment (which
is ignored) instead of the default of '#'.
Allow empty value
(right hand side).
all upper case letters in the key are folded to lower case. This flag disables
that behavior. This is intended to mesh with the -f flag in
the K line in sendmail.cf. The value
is never case folded.
Include the null byte that terminates strings in the map. This must match
the -N flag in the K line in sendmail.cf

a key, and does not do the insert.

Note that, if the -t option is also provided, the specified delimiter
is used when the content is dumped instead of whitespace.
