Fairly large files (the command files) are built in this directory during
the test runs, and even larger files (the database files) are created in
"/var/tmp". If the latter directory doesn't exist, set the environmental
variable TMPDIR to a directory where the files can be built.

The script file consists of lines with an initial character which is
the command for that line, or an initial character indicating a key
or data entry for a previous command.
Legal command characters are as follows:
c: compare a record
+ must be followed by [kK][dD]; the data value in the database
associated with the specified key is compared to the specified
data value.
e: echo a string
+ writes out the rest of the line into the output file; if the
last character is not a carriage-return, a newline is appended.
f: set the flags for the next command
+ no value zero's the flags
g: do a get command
+ must be followed by [kK]
+ writes out the retrieved data DBT.
o [r]: dump [reverse]
+ dump the database out, if 'r' is set, in reverse order.
p: do a put command
+ must be followed by [kK][dD]
r: do a del command
+ must be followed by [kK] unless R_CURSOR flag set.
S: sync the database
s: do a seq command
+ must be followed by [kK] if R_CURSOR flag set.
+ writes out the retrieved data DBT.
Legal key/data characters are as follows:
D [file]: data file
+ set the current data value to the contents of the file
d [data]:
+ set the current key value to the contents of the line.
K [file]: key file
+ set the current key value to the contents of the file
k [data]:
+ set the current key value to the contents of the line.
Blank lines, lines with leading white space, and lines with leading
hash marks (#) are ignored.
Options to dbtest are as follows:
-d: Set the DB_LOCK flag.
-f: Use the file argument as the database file.
-i: Use the rest of the argument to set elements in the info
structure. If the type is btree, then "-i cachesize=10240"
will set BTREEINFO.cachesize to 10240.
-o: The rest of the argument is the output file instead of
using stdout.
-s: Don't delete the database file before opening it, i.e.
use the database file from a previous run.
Dbtest requires two arguments, the type of access "hash", "recno"
or "btree", and the script name or "-" to indicate stdin.
