The ExPex package provides very fine-grained control over glossing and example formatting, including unlimited gloss lines and various ways of formatting multiline glosses. By contrast the cgloss4e glossing macros provided with gb4e, linguex, and covington, although very capable at basic glossing, lack the degree of customization that is sometimes needed for more complex glossing. This package is an attempt to have the best of both worlds: it allows gb4e, linguex and covington users to keep using those packages for basic example numbering and formatting, but also allows them to use the glossing macros that ExPex provides.
