# This program looks for texinfo snippets in source files and other
|
|
# files, and builds per-category files with entries sorted in
|
|
# alphabetical order.
|
|
|
|
# The syntax it looks for is lines starting with '@def' in *.c and
|
|
# other files (see TEXIFILES in Makefile.in). Entries are terminated
|
|
# at the next @def* (which begins a new entry) or, for C files, a line
|
|
# that begins with '*/' without leading spaces (this assumes that the
|
|
# texinfo snippet is within a C-style /* */ comment).
