# Updated January 14, 2004 to record the type of definition (defmacro,
# defun, etc.) and to avoid finding definitions in comments and strings.
#
# Produce a list of macros and the packages/files in which they are defined.
# Usage: find $package_root -type f -name \*.el | \
#        xargs awk -f gen-macro-list.awk > macro.list
#
# Find all instances of defmacro and defsubst (including defmacro*, etc.)
# not in comments or strings
