dnl modern.m4: a modern and simple framework for using the m4 macro language

dnl

dnl This file is covered by COPYING.SOFORT.

dnl

dnl 1) make all standard m4 builtins m4_ prefixed.

dnl 2) set the left-bracket and right-bracket symbols the begin-quote and end-quote strings.

dnl 3) make a single underscore symbol the equivalent of the standard dnl builtin.

dnl 4) provide the m4_toupper(), m4_tolower(), and m4_pathvar() macros.

dnl 5) provide the m4_srclist() and m4_srcitem() macros.

dnl 6) provide the m4_fillerdots(), m4_fillerdash(), and m4_fillerline() macros.

dnl 7) provide the m4_whitespace() and m4_spacealign() macros.

dnl 8) provide the m4_alignlen(), m4_leftalign(), and m4_rightalign() macros.

dnl 9) provide the m4_tab(), m4_tabtab(), and m4_tabtabtab() macros.
