  * Function:    generate_test_file
  *
  * Purpose:     This function is called to produce an HDF5 data file
- *              whose superblock is relocated to a non-zero offset by
- *              utilizing the 'h5jam' utility to write random text
- *              at the start of the file.  Unlike simple concatenation
- *              of files, h5jam is used to place the superblock on a
- *              power-of-2 boundary.
+ *              whose superblock is relocated to a power-of-2 boundary.
  *
  *              Since data will be read back and validated, we generate
  *              data in a predictable manner rather than randomly.
