        Creates a database file.
    kchashmgr inform [-onl|-otl|-onr] [-st] path
        Prints status information.
    kchashmgr set [-onl|-otl|-onr] [-add|-app|-rep|-inci|-incd] [-sx] path key value

        Prints the value of a record.
    kchashmgr list [-onl|-otl|-onr] [-max num] [-rm] [-sx] [-pv] [-px] path [key]
        Prints keys of all records, separated by line feeds.
    kchashmgr clear [-onl|-otl|-onr] path
        Removes all records of a database.
    kchashmgr import [-onl|-otl|-onr] [-sx] path [file]
        Imports records from a TSV file.
    kchashmgr copy [-onl|-otl|-onr] path file
        Copies the whole database.
    kchashmgr dump [-onl|-otl|-onr] path [file]
        Dumps records into a snapshot file.
    kchashmgr load [-otr] [-onl|-otl|-onr] path [file]
        Loads records from a snapshot file.
    kchashmgr defrag [-onl|-otl|-onr] path
        Performs defragmentation.
    kchashmgr setbulk [-onl|-otl|-onr] path key value ...
        Store records at once.
    kchashmgr removebulk [-onl|-otl|-onr] [-sx] path key ...
        Remove records at once.
    kchashmgr getbulk [-onl|-otl|-onr] [-sx] [-px] path key ...
        Retrieve records at once.
    kchashmgr check [-onl|-otl|-onr] path
        Checks consistency.

Options feature the following.

    -otr : opens the database with the truncation option.
    -onl : opens the database with the no locking option.
    -otl : opens the database with the try locking option.
    -onr : opens the database with the no auto repair option.
    -apow num : specifies the power of the alignment of record size.
    -fpow num : specifies the power of the capacity of the free block pool.
    -ts : tunes the database with the small option.
    -tl : tunes the database with the linear option.
    -tc : tunes the database with the compression option.
    -bnum num : specifies the number of buckets of the hash table.
    -st : prints miscellaneous information.
    -add : performs adding operation.
    -app : performs appending operation.
    -rep : performs replacing operation.
    -inci : performs integer increment operation.
    -incd : performs real number increment operation.
    -sx : the input data is evaluated as a hexadecimal data string.
    -rm : removes the record.
    -px : the output data is converted into a hexadecimal data string.
    -pz : does not append line feed at the end of the output.
    -max num : specifies the maximum number of shown records.
