% Here is a version of Adrian's VERBATIM.STY, for inputting whole files
% verbatim, which is "more LaTeX-like" in that it uses the actual LaTeX 
% macros which set up the `verbatim' environment.
%
% As a matter  of interest, it is much nicer for TeX if you input large
% quantities of "verbatim material" from an "external file" rather than by use 
% of the `verbatim' environment (i.e. putting the material in the main input 
% file. This is because this environment, in common with most (but not all)
% other "verbatim macros", makes the whole of the "vebatim material" a macro
% argument and therefore eats up TeTeX's internal memory.

%
% --- This LaTeX style-file defines two user-callable macros:
% ---     \verbatimfile{<filename>}    for verbatim inclusion of a file
% ---     \verbatimlisting{<filename>} for verbatim inclusion with line numbers
%
% --- The macros are based on those distributed with Sunil Podar's
% --- `EPIC.STY' macro package, attributed to Tim Morgan,
% --- modified to keep internal macros internal by Adrian F. Clark,
% --- alien@uk.ac.essex.ese
% --- ---and further latexification by Chris Rowley,
% --- ca_rowley@uk.ac.open.acs.vax.
%
% --- Note that the precise layout of line breaks in this file is important!
