git-untracked-files

#!/bin/bash
#
# List all files not tracked by git (including the .git repository) in a
# regular-expression format expected by CMake/CPack. This will be passed
# to CPack's CPACK_IGNORE_FILES variable for ignoring while making the
# source/binary packages, and also stored in .cpackignore file.
#
# If more than two command line arguments are given, the second and higher
# arguments are taken as subdirectories (relative to the source root
# directory) to exclude in entirety. This allows you to exclude directories
# that are tracked in git, but you don't want in the final source
# distribution.
#
# If there's no .git directory, or git is not installed, look for
# .cpackignore file.  This may happen if we're building the source outside
# of a git repository (or if there's no git on the system).
#
# Usage: git-untracked-files [dir_from_which_to_run] [extra_dir_to_exclude [extra_dir_to_exclude [..]]]
