+This file belongs to the MFTOEPS package.
+
+-----------------------------------------------------------------------------
+
+OVERVIEW
+
+The package MFTOEPS belongs to the public domain. You are entitled to do with
+the files of which it consists whatever you wish. If you alter a file,
+however, please remove the line containing the comment
+
+ `This file belongs to the MFTOEPS package.'
+
+in order to avoid a mess.
+
+The kernel of this little package is the METAFONT program MFTOEPS.MF written
+by Bogus\l{}aw Jackowski, Piotr Pianowski and Marek Ry\'cko. The aim of the
+program is to produce EPS (encapsulated PostScript) files readable by
+CorelDRAW!(R), Adobe Illustrator(TM) and Fontographer(R).
+
+The user of the package is supposed to be familiar a bit with METAFONT and
+PostScript. Donald E. Knuth's ``The METAFONTbook'' and Adobe's ``PostScript
+Language Reference Manual'' (both by Addison-Wesley Publishing Company, Inc.)
+should be consulted in the case of doubts.
+
+There is a bunch of simple examples in the subdirectory M2ESAMP. The
+directory ../PROGS contains DOS batch files and other programs which,
+possibly after some adjustments, can be used to generate EPS files.
+
+Roughly, the machinery works as follows: the resulting PostScript code
+is written by METAFONT to a LOG file; the LOG file is then processed
+either by AWK or by TeX (see the PROGS subdirectory) in order to extract
+the PostScript code. The idea seems straightforward; however, even
+a partial conciliation of the worlds of CorelDRAW! and Adobe Illustrator
+was not so much straightforward.
+
+-----------------------------------------------------------------------------
+
+In addition to the main MFTOEPS package, there are two ``bonus'' packages in
+directories ../EPSTOMF and ../ROEX. EPSTOMF converts ``canonical'' EPS files,
+i.e., files conforming the structure of the files generated by the MFTOEPS
+package, into the METAFONT lingo; ROEX is a set of METAFONT macros
+accomplishing the task of removing overlaps and expanding strokes (for
+details see there).
+
+-----------------------------------------------------------------------------
+
+INTERFACE SYNOPSIS
+
+Conventions: In the following we shall use words `number,' `pair,' `string,'
+and `path' as an abbreviation for `numeric expression,' `pair expression,'
+`string expression,' and `path expression,' respectively. The signs `less'
+and `greater,' used for marking parameters of macros, are
+``meta-characters,'' i.e., they do not belong to the METAFONT code.
+
+There are fifteen interface macros defined in the MFTOEPS.MF file:
+ eps_mode_setup
+ write_preamble
+ write_postamble
+ set_BB
+ find_BB
+ reset_BB
+ fill_C
+ draw_C
+ clip_C
+ fix_line_width
+ fix_line_join
+ fix_line_cap
+ fix_line_miter_limit
+ fix_fill_cmyk
+ fix_draw_cmyk
+
+COMMAND eps_mode_setup
+USAGE eps_mode_setup <an optional number (0 or 1)>;
+REMARKS This command should be used instead of the usual |mode_setup|
+ command. The forms |EPS_mode_setup| and |EPS_mode_setup 1|
+ are equivalent. One of them (preferably the former one) should
+ be used for normal processing. Invoking |EPS_mode_setup 0|
+ is meant primariliy for testing purposes and is supposed
+ to be used by experienced programmers who know what they are doing.
+ There are two predefined constants in MFTOEPS.MF to be used in this
+ context, namely, |no_export_level=0| and |compatibility_level=1|.
+ It is advisable to use the names of the constants rather than
+ bare numbers.
+
+COMMAND write_preamble
+USAGE write_preamble <string>;
+REMARKS This command initialises the process of writing of the PostScript
+ code. The string expression is the name (without extension)
+ of the resulting EPS file; the extension is always |.EPS|.
+ METAFONT is switched to the |batchmode| in order to avoid
+ slowing down the process by writing mess(ages) to the terminal.
+ The inspection of the log file is thus highly recommended.
+
+COMMAND write_postamble
+USAGE write_postamble;
+REMARKS This command ends writing of the PostScript code, switches METAFONT
+ back to the |errorstopmode|, and performs neccessary ``last minute''
+ actions (see below).
+
+COMMANDS set_BB find_BB reset_BB
+USAGE set_BB <four numbers or two pairs separated by commas>;
+ find_BB <a list of paths separated by commas>;
+ reset_BB;
+REMARKS Commands |set_BB| or |find_BB| should be invoked prior to
+ invoking |write_preamble|. |set_BB| sets the coordinates of
+ the corners of the bounding box of a graphic object; it is
+ useful when the bounding box of a graphic object is
+ known in advance or if it is required to force an artificial
+ bounding box. |find_BB| computes the respective bounding box
+ for a list of paths; if several |find_BB| statements are
+ used, the common bounding box is calculated for all paths
+ that appeared in the arguments. The result is stored in the
+ variables |xl_crd|, |yl_crd|, |xh_crd|, and |yh_crd|. There
+ are two functions, |llxy| and |urxy|, returning pairs
+ |(xl_crd,yl_crd)| and |(xh_crd,yh_crd)|, respectively. The
+ last command, |reset_BB|, makes |xl_crd|, |yl_crd|,
+ |xh_crd|, and |yh_crd| undefined (the initial situation);
+ |reset_BB| is performed by the |write_postamble| macro,
+ which is convenient in the case of generating several
+ several EPS files in a single METAFONT run.
+
+COMMANDS fill_C draw_C
+USAGE fill_C <a list of paths separated by commas>;
+ draw_C <a list of paths separated by commas>;
+REMARKS These commands are to be used instead of the usual
+ METAFONT |fill| and |draw| ones. They cause that a list of paths
+ followed by the PostScript operation |eofill| (|fill_C|) or |stroke|
+ (|draw_C|) is translated to a PostScript code. The list of paths
+ constitutes a single curve in the sense of PostScript.
+
+COMMAND clip_C
+USAGE clip_C <a list of paths separated by commas, possibly empty>;
+REMARKS The macro |clip_C| with a non-empty parameter works similarly to
+ the |fill_C| command, except that the |eoclip| operator is issued
+ instead of |eofill|. This causes an appropriate change of
+ the current clipping area. According to PostScript's principles,
+ the resulting area is a set product of the current clipping
+ area and the area specified in the argument of the |eoclip|
+ command. The empty parameter marks the end of the scope
+ of the most recent |clip_C| command with a non-empty parameter.
+ In other words, nested |clip_C| commands form a ``stack'' structure.
+ If needed, the appropriate number of parameterless |clip_C|
+ commands is issued by the |write_postamble| macro, thus
+ the user needs not to care about it.
+ WARNING: files produced with the use of |clip_C| are
+ interpreted properly by Adobe Illustrator (provided paths
+ directions are defined properly) but not by CorelDRAW! (ver. 3.0).
+
+COMMANDS fix_line_width fix_line_join fix_line_cap fix_miter_limit fix_dash
+USAGE fix_line_width <a non-negative number (dimension)>;
+ fix_line_join <a number (0, 1 or 2)>;
+ fix_line_cap <a number (0, 1 or 2)>;
+ fix_miter_limit <a number greater or equal 1>;
+ fix_dash (<a list of numbers (dimensions), possibly empty>)
+ <number (dimension)>;
+REMARKS These command are to be used in connection with the |draw_C|
+ command. |fix_line_width| fixes the thickness of the outline.
+ The other three commands correspond to PostScript operations
+ |setlinejoin|, |setlinecap|, |setmiterlimit|, and |setdash| (see
+ ``PostScript Language Reference Journal'' for details).
+
+ All commands should be used after |write_preamble|, as
+ |write_preamble| sets the default thickness (0.4pt), default
+ line join (0), default line cap (0), default miter limit (10),
+ and a solid line as a default for stroking (|fix_dash () 0|).
+
+COMMANDS fix_fill_cmyk fix_draw_cmyk
+USAGE fix_fill_cmyk <four numbers separated by commas>;
+ fix_draw_cmyk <four numbers separated by commas>;
+REMARKS These commands define the colours of the interiors of graphic
+ objects (|fix_fill_cmyk|) and colours of outlines (|fix_draw_cmyk|)
+ using cyan-magenta-yellow-black model (basic model). They should
+ be used after |write_preamble| (because |write_preamble| defines
+ the black colour as a default for both macros) and prior to invoking
+ the corresponding |fill_C| and |draw_C| commands, respectively.
+ There are also (just in case) macros |fix_fill_rgb| and
+ |fix_draw_rgb| using red-green-blue model; the argument to both
+ macros is a triple of numbers. (The user can control the process
+ of conversion from RGB to CMYK by the redefinition of macros
+ |under_color_removal| and |black_generation|.) The numbers
+ forming the arguments of the macros are supposed to belong to
+ the interval [0..1].
+
+ADDITIONAL FUNCTIONS pos_turn neg_turn
+USAGE pos_turn <primary path expression>
+ neg_turn <primary path expression>
+REMARKS Each function returns the path passed as the argument,
+ except that the orientation of the path is changed, if
+ necessary: |pos_turn| returns paths oriented anti-clockwise,
+ |neg_turn|---oriented clockwise. This may be
+ usefull for creation pictures which are to be processed
+ further by Adobe Illustrator, because this program is
+ sensitive to the orientation of paths.
+
+CONTROL VARIABLES yeseps yesEPS YESEPS
+REMARKS No EPS file will be generated unless one variable among
+ |yeseps| or |yesEPS| or |YESEPS| is assigned a definite value.
+ It is advisable to set this variable in a command line
+ (see M2E.BAT and M2E-ALT.BAT in the PROGS directory).
+ In fact, using |yeseps| is reccomended. Aliases |yesEPS|
+ and |YESEPS| were introduced for ``historical'' reasons.
+
+CONTROL VARIABLE testing
+REMARKS If the variable |testing| is assigned a definite value, the whole
+ PostScript code is flushed to the terminal, thus slowing
+ down significantly the process of generation of an EPS file
+ (cf. the description of the |write_preamble| command).
+
+-----------------------------------------------------------------------------
+
+ENCOURAGEMENT
+
+The inspection of the source code of the MFTOEPS.MF program may reveal
+a few more useful macros.
