+To run the tests, enter "make regress".
+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.

+# regular expression test set
+# Lines are at least three fields, separated by one or more tabs.  "" stands
+# for an empty field.  First field is an RE.  Second field is flags.  If
+# C flag given, regcomp() is expected to fail, and the third field is the
+# error name (minus the leading REG_).
+#
+# Otherwise it is expected to succeed, and the third field is the string to
+# try matching it against.  If there is no fourth field, the match is
+# expected to fail.  If there is a fourth field, it is the substring that
+# the RE is expected to match.  If there is a fifth field, it is a comma-
+# separated list of what the subexpressions should match, with - indicating
+# no match for that one.  In both the fourth and fifth fields, a (sub)field
+# starting with @ indicates that the (sub)expression is expected to match
+# a null string followed by the stuff after the @; this provides a way to
+# test where null strings match.  The character `N' in REs and strings
+# is newline, `S' is space, `T' is tab, `Z' is NUL.
+#
+# The full list of flags:
+#       -       placeholder, does nothing
