From 21fa5f06a23249786df80fb4310d2284fe8d66e2 Mon Sep 17 00:00:00 2001 From: Murray Stokely Date: Mon, 4 Mar 2002 06:46:05 +0000 Subject: [PATCH] Move the developer entities out to a separate include file, so that these entities may be used by other documents. Also, prepend "a." to the developer entities, to clearly define the namespace used for this purpose (as done in doc/). --- en/developers.sgml | 40 ++++++++ en/smp/index.sgml | 230 +++++++++++++++++++++------------------------ 2 files changed, 147 insertions(+), 123 deletions(-) create mode 100644 en/developers.sgml diff --git a/en/developers.sgml b/en/developers.sgml new file mode 100644 index 0000000000..db430bf44c --- /dev/null +++ b/en/developers.sgml @@ -0,0 +1,40 @@ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + diff --git a/en/smp/index.sgml b/en/smp/index.sgml index f9109e3365..5a6fd525d4 100644 --- a/en/smp/index.sgml +++ b/en/smp/index.sgml @@ -1,6 +1,6 @@ - + %includes; @@ -13,27 +13,11 @@ Resolved"> Unresolved"> - - - - - - - - - - - - - - - - - - - - - + + + %developers; + ]> @@ -114,7 +98,7 @@ project page that contains additional information, and goes back further in time than this web page.
