automatically be expanded to include useful information about the checkin (including the file's revision number). With the switch over to SVN this was lost because SVN only does this expansion if you explicitly ask for it (for every single file). I have added a script to the contrib directory that sets the appropriate property to get SVN to do this expansion. This script will make it easy to do this every time new source files are added. It is called svn_expand_Id, the script contains some comments that explain the issue and how it addresses this. This checkin sets this property for a subset of the relevant files (trying to commit all files at once failed with svn crashing). In future the script will only affect those files for which the property was not set before.

% More modifications by J. Daniel Smith on 29 March 1991 to allow the
|
|
% the included PostScript figure to be rotated. The amount of
|
|
% rotation is specified by the "angle=" parameter of the \psfig command.
|
|
%
|
|
% Modified by Robert Russell on June 25, 1991 to allow users to specify
|
|
% .ps filenames which don't yet exist, provided they explicitly provide
|
|
% boundingbox information via the \psfig command. Note: This will only work
|
|
% if the "file=" parameter follows all four "bb???=" parameters in the
|
|
% command. This is due to the order in which psfig interprets these params.
|
|
%
|
|
% 3 Jul 1991 JDS check if file already read in once
|
|
% 4 Sep 1991 JDS fixed incorrect computation of rotated
|
|
% bounding box
|
|
% 25 Sep 1991 GVR expanded synopsis of \psfig
|
|
% 14 Oct 1991 JDS \fbox code from LaTeX so \psdraft works with TeX
|
|
% changed \typeout to \ps@typeout
|
|
% 17 Oct 1991 JDS added \psscalefirst and \psrotatefirst

|
|
% \psdraft draws an outline box, but doesn't include the figure
|
|
% in the DVI file. Useful for previewing.
|
|
%
|
|
% \psfull includes the figure in the DVI file (default).
|
|
%
|
|
% \psscalefirst width= or height= specifies the size of the figure
|
|
% before rotation.
|
|
% \psrotatefirst (default) width= or height= specifies the size of the
|
|
% figure after rotation. Asymetric figures will
|
|
% appear to shrink.
|
|
%
|
|
% \psfigurepath#1 sets the path to search for the figure
|
|
%

|
|
% usage: \psfig{file=, figure=, height=, width=,
|
|
% bbllx=, bblly=, bburx=, bbury=,

% rheight=, rwidth=, clip=, angle=, silent=}
|
|
%
|
|
% "file" is the filename. If no path name is specified and the
|
|
% file is not found in the current directory,
|
|
% it will be looked for in directory \psfigurepath.
|
|
% "figure" is a synonym for "file".
|
|
% By default, the width and height of the figure are taken from
|
|
% the BoundingBox of the figure.
|
|
% If "width" is specified, the figure is scaled so that it has
|
|
% the specified width. Its height changes proportionately.
|
|
% If "height" is specified, the figure is scaled so that it has
|
|
% the specified height. Its width changes proportionately.
|
|
% If both "width" and "height" are specified, the figure is scaled
|
|
% anamorphically.
|
|
% "bbllx", "bblly", "bburx", and "bbury" control the PostScript
|
|
% BoundingBox. If these four values are specified
|
|
% *before* the "file" option, the PSFIG will not try to
|
|
% open the PostScript file.
|
|
% "rheight" and "rwidth" are the reserved height and width
|
|
% of the figure, i.e., how big TeX actually thinks
|
|
% the figure is. They default to "width" and "height".
|
|
% The "clip" option ensures that no portion of the figure will
|
|
% appear outside its BoundingBox. "clip=" is a switch and
|
|
% takes no value, but the `=' must be present.
|
|
% The "angle" option specifies the angle of rotation (degrees, ccw).
|
|
% The "silent" option makes \psfig work silently.
