-% \section{What is this all about?}
-%
-% In Greece, until recently, it was common practice to write down most
-% log-like functions as abbreviations of their Greek names. Consequently,
-% high school students and even university freshmen were not familiar with
-% the Latin names employed in international literature. However, this practice
-% is fading away in universities but it is still in wide use in books for
-% high schools, mainly because the Latin names would produce nothing but
-% confusion. The package |grmath| redefines most log-like definitions
-% so that they produce the Greek name, instead of the Latin one. The package
-% can be used only in conjunction with the |greek| option of the |babel|
-% package. The new option |enlog| allows one to keep the Latin names for
-% the log functions.

-% \section{The Implementation}
-%
-% As usual we must first identify ourselves.
-%
-% \begin{macrocode}
-%<*package>
-\ProvidesPackage{grmath}[2001/02/12\space v1.2]
-\typeout{Package: `grmath' v1.2\space <2001/02/12> (A. Syropoulos)}
-% \end{macrocode}
-%
-% The next thing we do is to process the options. The default option
-% ``grlog'' generates Greek names for log functions and the ``enlog''
-% option generates Latin names for log functions.
-% \begin{macrocode}
-\DeclareOption{grlog}{%
- \def\log{\mathop{\mathgroup\symgroperators log_{10}}\nolimits}
- \def\ln{\mathop{\mathgroup\symgroperators log_%
- {\mathgroup\symoperators e}}\nolimits}
-}
-\DeclareOption{enlog}{%
- \def\log{\mathop{\operator@font log}\nolimits}
- \def\ln{\mathop{\operator@font ln}\nolimits}
-}
-\ExecuteOptions{grlog}
-\ProcessOptions
-% \end{macrocode}
-%
-% Now we check to see if the |babel| package is loaded with at least
-% the |greek| option. In case it isn't, we opt to produce an error message.
-% \begin{macrocode}
-\@ifpackagewith{babel}{greek}{}{%
- \@ifpackagewith{babel}{polutonikogreek}{}{%
- \PackageError{grmath}{%
- `greek' option of the `babel'\MessageBreak
- package hasn't been loaded}{%
- The commands provided by this package\MessageBreak
- are specially designed for greek language\MessageBreak
- typesetting with the `babel' package. Load\MessageBreak
- it with at least the `greek' option.}\relax
- }}
-% \end{macrocode}
-%
-% We define the mathematical font which will be used to typeset
-% the log-like functions.
-% \begin{macrocode}
-\DeclareSymbolFont{groperators}{LGR}{cmr}{m}{n}
-\SetSymbolFont{groperators}{bold}{LGR}{cmr}{bx}{n}
-% \end{macrocode}
-%
-% We are now ready to proceed with the redefinitions of the log-like
-% operator names.
-% \begin{macrocode}
-\def\sin{\mathop{\mathgroup\symgroperators hm}\nolimits}
-\def\cos{\mathop{\mathgroup\symgroperators sun}\nolimits}
-\def\tan{\mathop{\mathgroup\symgroperators ef}\nolimits}
-\def\arcsin{\mathop{\mathgroup\symgroperators toxhm}\nolimits}
-\def\arccos{\mathop{\mathgroup\symgroperators toxsun}\nolimits}
-\def\arctan{\mathop{\mathgroup\symgroperators toxef}\nolimits}
-\def\cot{\mathop{\mathgroup\symgroperators sf}\nolimits}
-\def\sec{\mathop{\mathgroup\symgroperators tem}\nolimits}
-\def\csc{\mathop{\mathgroup\symgroperators stem}\nolimits}
-\def\gcd{\mathop{\mathgroup\symgroperators MKD}\nolimits}
-% \end{macrocode}
-% In the standard \LaTeX\ distribution there is no provision for a
-% Least Common Multiple (lcm) log-like operator. Since, this operator
-% appears quite often in greek literature we opt to include it. Moreover,
-% we include three more log-like functions: |\arccot|, |\arcsec| and
-% |\arccsc|.
-% \begin{macrocode}
-\def\lcm{\mathop{\mathgroup\symgroperators EKP}\nolimits}
-\def\arccot{\mathop{\mathgroup\symgroperators toxsf}\nolimits}
-\def\arcsec{\mathop{\mathgroup\symgroperators toxtem}\nolimits}
