| # 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). |
