Remove + option --no-cache. Use associative arrays when supported by the shell. + (sed_comments): New variable. + (modcache): Renamed from do_cache. + (sed_extract_field_header): Renamed from sed_extract_cache_prog. Don't + abbreviate unnecessarily. + (have_associative): New variable. + (func_cache_var): Define correctly for bash 1.x. Define in an optimized + way also for ksh and zsh. + (func_init_sed_convert_to_cache_statements): New function, extracted + from func_cache_lookup_module. Add support for associative arrays. + Don't set the c_MODULE_cached variable here. Ignore all lines before + the first field header. Remove only the final newline, not all trailing + newlines. Support empty fields correctly. Limit the use of 'eval' to + assignments. + (func_get_description, func_get_status, func_get_notice, + func_get_applicability, func_get_filelist, func_get_dependencies, + func_get_autoconf_early_snippet, func_get_autoconf_snippet, + func_get_automake_snippet, func_get_include_directive, + func_get_link_directive, func_get_license, func_get_maintainer): + Update documentation. List the unoptimized code first. Add support for + associative arrays. Limit the use of 'eval' to assignments. + (func_get_applicability): Undo stylistic pessimisations. + (func_get_automake_snippet, func_get_include_directive): Reduce code + duplication. + (func_modules_transitive_closure, func_modules_add_dummy, + func_modules_notice, func_modules_to_filelist, func_add_file, + func_update_file, func_emit_lib_Makefile_am, func_emit_po_Makevars, + func_emit_po_POTFILES_in, func_emit_tests_Makefile_am, func_import, + func_create_testdir, func_create_megatestdir): Update documentation. + 2010-01-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> * gnulib-tool (func_cache_lookup_module): Store the module name
