# Add regex patterns here to exclude paths from scanning.

# One pattern per line. Lines starting with # are comments.

#

# Examples:

# ^/proc/.* - Exclude everything under /proc

# .*\.log$ - Exclude all .log files

# .*node_modules.* - Exclude node_modules directories

#

# See config/excludes.cfg.example for more examples.
