5 # Synopsis: This program uses "cvs annotate" to get a summary of how many lines
6 # of code the various developres are responsible for. It takes one
7 # argument, the directory to process. If the argument is not specified
8 # then the cwd is used. The directory must be an LLVM tree checked out
11 # Syntax: userloc.pl [-tag=tag|-html... <directory>...
15 # Use "tag" to select the revision (as per cvs -r option)
17 # Report details about lines of code in each file for each user
19 # Generate HTML output instead of text output
21 # Specify where the top llvm source directory is. Otherwise the
22 # llvm-config tool is used to find it.
24 # The directories passed after the options should be relative paths to
25 # directories of interest from the top of the llvm source tree, e.g. "lib"
