+
+LaTeX separates its internal notion of font specification
+from the external fonts available on the system by means of
+`Font Shape Specifications', that are normally held in
+`Font Descriptor' (fd) files.
+
+The fd files that come with LaTeX that refer to the standard
+Computer Modern set (and the related AMS set) are based on
+the classical bitmap fonts which are available in `magstep'
+sizes only. For instance The specification of the main roman font is
+ \DeclareFontShape{OT1}{cmr}{m}{n}
+ { <5> <6> <7> <8> <9> <10> <12> gen * cmr
+ <10.95> cmr10
+ <14.4> cmr12
+ <17.28><20.74><24.88>cmr17}{}
+which says for instance that no font is available at 10.5pt (LaTeX
+will substitute the nearest available size if you ask for this)
+and similarly the font is not available at all above 25pt.
+
+Such restrictions are essential with bitmap fonts to save generating
+huge numbers of bitmaps for any size that might be requested, however
+with scalable versions of the fonts these restrictions are not really
+needed. For instance the equivalent definition defined here is:
+\DeclareFontShape{OT1}{cmr}{m}{n}{
+ <-6> cmr5
+ <6-7> cmr6
+ <7-8> cmr7
+ <8-9> cmr8
+ <9-10> cmr9
+ <10-12> cmr10
+ <12-17> cmr12
+ <17-> cmr17
+ }{}
+
+which means that you can (Although some may consider it bad style)
+go \fontsize{10.7pt}{12pt}\selectfont and be given a suitably scaled
+version of cmr10 and a baseline setting of 12pt. Similarly if you really
+want, you can go \fontsize{2cm}{2.5cm}\selectfont and use cmr17 scaled
+to 2cm height for a special display context.
+
+**** Warning****
+If you use this setup and produce dvi files using these sizes, be very
+careful if you give the dvi files so created to someone using classical
+bitmap versions of the cm fonts. Depending on how their system is set up
+they will either not be able to print the file at all, as they will not
+have the fonts at the corrrect sizes, or the system will make all these
+strange sizes `on demand' and fill the disk with bitmaps.
+****************
+
+So the default way of using this package is as a LaTeX package file.
+Install type1cm.sty as described below and then just add
+\usepackage{type1cm}
+to your document. This will override the definitions for all the fonts
+and so the standard fd files are not used.
+The disadvantage of this method is all the definitions are then loaded
+into memory, even for fonts you don't use in the document. (However
+only the size specifications are so loaded, not the fonts themselves).
+However the advantage is that you can always choose not to specify
+\usepackage{type1cm} and so use the same font sizes (and get the
+same line and page breaks) as everyone else.
+
+Alternatively you may use this package to produce a set of fd
+files that *replace* the standard files (such as ot1cmr.fd)
+You will then need to remake the LaTeX format by running initex on
+latex.ltx (as some fd files are loaded into the format). Then you
+will not need to use \usepackage. All your documents will have the
+freedom of scalable font choices.
+
+ INSTALLATION INSTRUCTIONS
+ ==========================
+
+The installation is controlled by the file type1cm.ins which you may
+edit in two places.
+
+
+1) If you have not got the AMS Font set available in scalable form
+ remove the `%' from the line %\def\ams{}
+ This will cause a more restricted font specification to be used.
+
+ If you have an extended AMS font set available in scalable form
+ (msam6, msam8 and msam9 in addition to msam5, msam7 and msam10)
+ then remove the `%' from the line %\def\ams{ams,extra}
+
+
+2) If after reading the warning above you decide to make a set of fd
+ files, remove the `%'from the line %\makefdtrue
+
+
+Then run tex (or latex) on the file type1cm.ins and a package file
+type1cm.sty (and perhaps a set of fd files) will be produced
+which you should place in a directory where TeX looks for input files.
+
+=========================================================================
+
+Small technical note about the Font Shape specifications used.
+I consistantly specified that given a requested size, the largest
+available font size smaller than the requested size should be used
+and then enlarged to the requested size. The exception being sizes
+smaller than the smallest available font, which use a reduced version
+of that font. The rationale for this is that enlarging a small font
+typically produces a rather `fat' font, but something readable, whereas
+shrinking a font may produce something unreadable quite quickly
+
+So for msam (if `extra' is not specified) I used:
+
+\DeclareFontShape{U}{msa}{m}{n}{
+ <-7> msam5
+ <7-10> msam7
+ <10-> msam10
+ }{}
+
+That is sizes strictly below 7pt use msam5, 7pt to (less than) 10pt
+use msam7 and sizes 10pt and above use msam10.
+
+This differs from the Specification that the AMS use for the scalable
+AMS fonts (used by the psfonts option to the amsfonts package)
+They use
+
+\DeclareFontShape{U}{msa}{m}{n}{
+ <-6> msam5
+ <6-8> msam7
+ <8-> msam10
+ }{}
+
+This has the advantage of minimising the scaling used, so for instance
+a 9pt request is satisfied by msam7 scaled up to 9 by this package, but
+by msam10 scaled down to 9 by the AMS package.
+
+In practice this is not likely to make a difference that anyone notices,
+but it could in principle affect line breaks etc, so I thought that
+I would mention it here.
