# Automatically fix one-line broken debug log calls. Adds a missing

# wrapper for such lines, e.g. changes:

#

# DUK_DPRINT(...);

#

# into:

#

# DUK_D(DUK_DPRINT(...));

#

# Does not handle multiline log calls.

#

# Usage:

#

# $ python autofix_debuglog_calls.py src-input/*.c

#

# WARNING: works in place, so commit any changes before running, then

# check diff.
