#print(output = STDOUT, options = {}) ⇒ Object

Specify print options.

options - Hash table

:min_percent - Number 0 to 100 that specifes the minimum
               self (the methods self time divided by the
               overall total time) that a method must take
               for it to be printed out in the report.
               Default value is 0.

:print_file  - True or false. Specifies if a method's source
               file should be printed.  Default value if false.

:threshold   - a float from 0 to 100 that sets the threshold of
               results displayed.
               Default value is 1.0

:title       - a String to overide the default "ruby-prof call tree"
               title of the report.

:expansion   - a float from 0 to 100 that sets the threshold of
               results that are expanded, if the percent_total
               exceeds it.
               Default value is 10.0

:application - a String to overide the name of the application,
               as it appears on the report.
