apseqnchar is a version of eqnchar tailored for the particular output
device Autologic APS-5; output will not look optimal on other devices.
cateqnchar is more "device-independent", and should produce output
that looks reasonable on any device supported by troff(1M).
By default, eqnchar is linked to cateqnchar.
