Имя (Name)
groff_tmac - macro files in the GNU roff typesetting system
Описание (Description)
Definitions of macros, strings, and registers for use in a
roff(7) document can be collected into macro files, roff input
files designed to produce no output themselves but instead ease
the preparation of other roff documents. There is no syntactical
difference between a macro file and any other roff document; only
its purpose distinguishes it. When a macro file is installed at
a standard location and suitable for use by a general audience,
it is often termed a macro package. Macro packages can be loaded
by supplying the -m option to groff(1) or troff(1).
Alternatively, a groff document wishing to use a macro package
can load it with the mso ('macro source') request.
Each macro package stores its macro, string, and register
definitions in one or more tmac files. This name originated in
early Unix culture as an abbreviation of 'troff macros'.
A macro package must be named name.tmac and be placed in a 'tmac
directory' to be loadable with the -m option. Section
'Environment' of troff(1) lists these directories. Like any
other roff document, a macro package can use the 'so' request
('source') to load further files relative to its own location.
