Unless you specify otherwise, your script receives %r/%p %<s -- that  
means: "the full path to a (temporary) directory in the server" as the  
script first argument, and "a list of filenames (one per line)" coming  
 from stdin.

pseudocode:

repo_dir = argv[1] # get first program argument
for each line in stdin:
     file_name = read_line(stdin)
     full_name = repo_dir + '/' + file_name
     # open full_name (if it exists) and validate its contents
     # anything you write to stdout will be echoed on the client side
# program exit code should be 0 if all went OK, and >0 to cancel the  
commit operation

(one invocation per directory; note that the file may have been just  
added, modified, or deleted)
