In addition to the production of a "date.txt" file by make, you can
pass such information through a file descriptor.  That avoids the
creation of a useless file.

Eg:

<!ENTITY date SYSTEM "<OSFD>3">

and pass the output of the date command through FD 3:

$ date | jade 3<&0 ....

It gets a bit more difficult when you need several FDs, but well...
