llvm-mirror/utils/userloc.pl
Reid Spencer 7f2ce5b626 Make all tools that use llvmdo have a -topdir option that allows the top
source dir for LLVM to be specified explicitly. This removes the dependency
on the llvm-config script. If the option is not given, then the scripts use
llvm-config which should be both built and in the PATH. This arrangement
provides a useful default for most developers but also allows the nightly
tester to execute countloc.sh before llvm-config is built and without
altering the PATH.

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