How do I make sure that .fmt files are put in a subdir of web2c by fmtutil? E.g. fmtutil --byfmt cont-en produces web2c/cont-en.fmt but what I want is web2c/pdftex/cont-en.fmt web2c/xetex/cont-en.fmt so cont-en.fmt is available for both pdfTeX and XeTeX and not one balks at finding a format produced by the other.
