  * Multi-function module. Can be compiled three ways.
  *
  *  - Compile with no special #defines. Will generate a table
  *    that's already initialised at compile time, and one function
- *    crc32(buf,len) that uses it. Normal usage.
+ *    crc32_compute(buf,len) that uses it. Normal usage.
  *
  *  - Compile with INITFUNC defined. Will generate an uninitialised
- *    array as the table, and as well as crc32(buf,len) it will
- *    also generate void crc32_init(void) which sets up the table
- *    at run time. Useful if binary size is important.
