How to verify lot of .sig files in lot of subdirectories with script

[Csabi]

Hi!

Can somebody help me?

I have lot of subdirectories containing program source code compressed 
files and their signature files.
For example: <program name> <program version>.tar.gz and
<program name> <program version>.tar.gz.sig
How do i verify lot of .sig files in lot of subdirectories with one script 
under Linux?
When i want to verify one .sig file i must give a complete path and 
filename to GNUPG and *.sig is not operate...
I havent Linux shell script programming knowledge to resolve the problem: 
the script search all .sig files in all subdirectory and call GNUPG to 
verify.

Sincerely, Csabi
