From 413c3a483a581516c1bc8cdc261fbbb8458622d5 Mon Sep 17 00:00:00 2001 From: Roland Pesch Date: Mon, 18 Jan 1993 23:59:57 +0000 Subject: [PATCH] Clean up readline doc subdir to conform to normal configure/distribution practices. Makefile: remove, replacing with a configurable Makefile.in texindex.c texinfo.tex: remove, replacing with references to tools elsewhere in Cygnus distribution tree. Makefile.in: configurable (and useable) Makefile. configure.in: pro forma configure stub. --- readline/doc/Makefile | 13 - readline/doc/Makefile.in | 94 ++ readline/doc/configure.in | 8 + readline/doc/texindex.c | 1606 --------------------- readline/doc/texinfo.tex | 2883 ------------------------------------- 5 files changed, 102 insertions(+), 4502 deletions(-) delete mode 100644 readline/doc/Makefile create mode 100644 readline/doc/Makefile.in create mode 100644 readline/doc/configure.in delete mode 100644 readline/doc/texindex.c delete mode 100644 readline/doc/texinfo.tex diff --git a/readline/doc/Makefile b/readline/doc/Makefile deleted file mode 100644 index 01e4bbb5df..0000000000 --- a/readline/doc/Makefile +++ /dev/null @@ -1,13 +0,0 @@ -# This file was generated automatically by configure.
