$(srcdir)/pdftexdir/tex.ch0 \
$(srcdir)/tex.ch \
$(srcdir)/pdftexdir/tex.ch1 \
$(srcdir)/pdftexdir/tex.pch
Input:
pdftex.web:
pdftex without system-dependent changes
pdftexdir/tex.ch0:
% Change file to assist in creating the web2c-specific change file.
% This one comes first, resolves inconsistencies between the
% generated pdftex.web and tex.ch
change the pdftex banner to tex banner, so tex.ch can be applied
tex.ch:
the main web2c-specific (or other system-dependent) change file
pdftexdir/pdftex.ch:
% Change file to assist in creating the web2c-specific change file.
% This one resolves inconsistencies between tex.ch and tex.pch.
