Help with replace line based on specific pattern match

Input file
Code:
data20714	7327	7366	detail	
data20714	7327	7366	main

data250821	56708	56779	main	
data250821	56532	56652	main	
.
.

Desired output file:
Code:

data250821	57527	57634	main	
data250821	57359	57474	main	
data250821	57212	57301	main	

data250821	56834	57082	main	
data250821	56708	56779	main	
data250821	56532	56652	main

My purpose is to replace the whole line with empty content when found that column 4 is "detail".
Thanks for any advice.

wibble-test-genrunner(1)				      General Commands Manual					  wibble-test-genrunner(1)

NAME
wibble-test-genrunner - Code generator for wibble testsuites. SYNOPSIS
wibble-test-genrunner header <file> wibble-test-genrunner main <files> DESCRIPTION
The program generates .cpp files that are then compiled and linked into a test program for running tests from .test.h files. Examples of such .test.h files may be found among wibble headers, eg. /usr/include/wibble/regexp.test.h. In the first form, the program processes a single header file (usually of the form foo.test.h) and produces a corresponding .cpp file to be compiled. In the second form, it takes as <files> all the .test.h headers and produces a single main.cpp which contains the main() function of the test program, which then runs all the tests in all the .test.h files. The generated source code is always written to standard output and it is left up to the user to redirect it to a meaningful location. The program currently has no options other than the two forms above. The program is intended to be run as part of build process of programs or libraries using the wibble testing framework. For convenient use from CMake, there is a test.cmake script under /usr/share/wibble, that takes care of producing all the .cpp files (both per-header and the main one), compiling them and linking them into a single binary which executes the testsuite.
