-		    GNU GENERAL PUBLIC LICENSE

-		       Version 2, June 1991

-

- Copyright (C) 1989, 1991 Free Software Foundation, Inc.

-                          675 Mass Ave, Cambridge, MA 02139, USA

- Everyone is permitted to copy and distribute verbatim copies

- of this license document, but changing it is not allowed.

-

-			    Preamble

-

-  The licenses for most software are designed to take away your

-freedom to share and change it.  By contrast, the GNU General Public

-License is intended to guarantee your freedom to share and change free

-software--to make sure the software is free for all its users.  This

-General Public License applies to most of the Free Software

-Foundation's software and to any other program whose authors commit to

-using it.  (Some other Free Software Foundation software is covered by

-the GNU Library General Public License instead.)  You can apply it to

-your programs, too.

-

-  When we speak of free software, we are referring to freedom, not

-price.  Our General Public Licenses are designed to make sure that you

-have the freedom to distribute copies of free software (and charge for

-this service if you wish), that you receive source code or can get it

-if you want it, that you can change the software or use pieces of it

-in new free programs; and that you know you can do these things.

-

-  To protect your rights, we need to make restrictions that forbid

-anyone to deny you these rights or to ask you to surrender the rights.

-These restrictions translate to certain responsibilities for you if you

-distribute copies of the software, or if you modify it.

-

-  For example, if you distribute copies of such a program, whether

-gratis or for a fee, you must give the recipients all the rights that

-you have.  You must make sure that they, too, receive or can get the

-source code.  And you must show them these terms so they know their

-rights.

-

-  We protect your rights with two steps: (1) copyright the software, and

-(2) offer you this license which gives you legal permission to copy,

-distribute and/or modify the software.

-

-  Also, for each author's protection and ours, we want to make certain

-that everyone understands that there is no warranty for this free

-software.  If the software is modified by someone else and passed on, we

-want its recipients to know that what they have is not the original, so

-that any problems introduced by others will not reflect on the original

-authors' reputations.

-

-  Finally, any free program is threatened constantly by software

-patents.  We wish to avoid the danger that redistributors of a free

-program will individually obtain patent licenses, in effect making the

-program proprietary.  To prevent this, we have made it clear that any

-patent must be licensed for everyone's free use or not licensed at all.

-

-  The precise terms and conditions for copying, distribution and

-modification follow.

-

-		    GNU GENERAL PUBLIC LICENSE

-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

-

-  0. This License applies to any program or other work which contains

-a notice placed by the copyright holder saying it may be distributed

-under the terms of this General Public License.  The "Program", below,

-refers to any such program or work, and a "work based on the Program"

-means either the Program or any derivative work under copyright law:

-that is to say, a work containing the Program or a portion of it,

-either verbatim or with modifications and/or translated into another

-language.  (Hereinafter, translation is included without limitation in

-the term "modification".)  Each licensee is addressed as "you".

-

-Activities other than copying, distribution and modification are not

-covered by this License; they are outside its scope.  The act of

-running the Program is not restricted, and the output from the Program

-is covered only if its contents constitute a work based on the

-Program (independent of having been made by running the Program).

-Whether that is true depends on what the Program does.

-

-  1. You may copy and distribute verbatim copies of the Program's

-source code as you receive it, in any medium, provided that you

-conspicuously and appropriately publish on each copy an appropriate

-copyright notice and disclaimer of warranty; keep intact all the

-notices that refer to this License and to the absence of any warranty;

-and give any other recipients of the Program a copy of this License

-along with the Program.

-

-You may charge a fee for the physical act of transferring a copy, and

-you may at your option offer warranty protection in exchange for a fee.

-

-  2. You may modify your copy or copies of the Program or any portion

-of it, thus forming a work based on the Program, and copy and

-distribute such modifications or work under the terms of Section 1

-above, provided that you also meet all of these conditions:

-

-    a) You must cause the modified files to carry prominent notices

-    stating that you changed the files and the date of any change.

-

-    b) You must cause any work that you distribute or publish, that in

-    whole or in part contains or is derived from the Program or any

-    part thereof, to be licensed as a whole at no charge to all third

-    parties under the terms of this License.

-

-    c) If the modified program normally reads commands interactively

-    when run, you must cause it, when started running for such

-    interactive use in the most ordinary way, to print or display an

-    announcement including an appropriate copyright notice and a

-    notice that there is no warranty (or else, saying that you provide

-    a warranty) and that users may redistribute the program under

-    these conditions, and telling the user how to view a copy of this

-    License.  (Exception: if the Program itself is interactive but

-    does not normally print such an announcement, your work based on

-    the Program is not required to print an announcement.)

-

-These requirements apply to the modified work as a whole.  If

-identifiable sections of that work are not derived from the Program,

-and can be reasonably considered independent and separate works in

-themselves, then this License, and its terms, do not apply to those

-sections when you distribute them as separate works.  But when you

-distribute the same sections as part of a whole which is a work based

-on the Program, the distribution of the whole must be on the terms of

-this License, whose permissions for other licensees extend to the

-entire whole, and thus to each and every part regardless of who wrote it.

-

-Thus, it is not the intent of this section to claim rights or contest

-your rights to work written entirely by you; rather, the intent is to

-exercise the right to control the distribution of derivative or

-collective works based on the Program.

-

-In addition, mere aggregation of another work not based on the Program

-with the Program (or with a work based on the Program) on a volume of

-a storage or distribution medium does not bring the other work under

-the scope of this License.

-

-  3. You may copy and distribute the Program (or a work based on it,

-under Section 2) in object code or executable form under the terms of

-Sections 1 and 2 above provided that you also do one of the following:

-

-    a) Accompany it with the complete corresponding machine-readable

-    source code, which must be distributed under the terms of Sections

-    1 and 2 above on a medium customarily used for software interchange; or,

-

-    b) Accompany it with a written offer, valid for at least three

-    years, to give any third party, for a charge no more than your

-    cost of physically performing source distribution, a complete

-    machine-readable copy of the corresponding source code, to be

-    distributed under the terms of Sections 1 and 2 above on a medium

-    customarily used for software interchange; or,

-

-    c) Accompany it with the information you received as to the offer

-    to distribute corresponding source code.  (This alternative is

-    allowed only for noncommercial distribution and only if you

-    received the program in object code or executable form with such

-    an offer, in accord with Subsection b above.)

-

-The source code for a work means the preferred form of the work for

-making modifications to it.  For an executable work, complete source

-code means all the source code for all modules it contains, plus any

-associated interface definition files, plus the scripts used to

-control compilation and installation of the executable.  However, as a

-special exception, the source code distributed need not include

-anything that is normally distributed (in either source or binary

-form) with the major components (compiler, kernel, and so on) of the

-operating system on which the executable runs, unless that component

-itself accompanies the executable.

-

-If distribution of executable or object code is made by offering

-access to copy from a designated place, then offering equivalent

-access to copy the source code from the same place counts as

-distribution of the source code, even though third parties are not

-compelled to copy the source along with the object code.

-

-  4. You may not copy, modify, sublicense, or distribute the Program

-except as expressly provided under this License.  Any attempt

-otherwise to copy, modify, sublicense or distribute the Program is

-void, and will automatically terminate your rights under this License.

-However, parties who have received copies, or rights, from you under

-this License will not have their licenses terminated so long as such

-parties remain in full compliance.

-

-  5. You are not required to accept this License, since you have not

-signed it.  However, nothing else grants you permission to modify or

-distribute the Program or its derivative works.  These actions are

-prohibited by law if you do not accept this License.  Therefore, by

-modifying or distributing the Program (or any work based on the

-Program), you indicate your acceptance of this License to do so, and

-all its terms and conditions for copying, distributing or modifying

-the Program or works based on it.

-

-  6. Each time you redistribute the Program (or any work based on the

-Program), the recipient automatically receives a license from the

-original licensor to copy, distribute or modify the Program subject to

-these terms and conditions.  You may not impose any further

-restrictions on the recipients' exercise of the rights granted herein.

-You are not responsible for enforcing compliance by third parties to

-this License.

-

-  7. If, as a consequence of a court judgment or allegation of patent

-infringement or for any other reason (not limited to patent issues),

-conditions are imposed on you (whether by court order, agreement or

-otherwise) that contradict the conditions of this License, they do not

-excuse you from the conditions of this License.  If you cannot

-distribute so as to satisfy simultaneously your obligations under this

-License and any other pertinent obligations, then as a consequence you

-may not distribute the Program at all.  For example, if a patent

-license would not permit royalty-free redistribution of the Program by

-all those who receive copies directly or indirectly through you, then

-the only way you could satisfy both it and this License would be to

-refrain entirely from distribution of the Program.

-

-If any portion of this section is held invalid or unenforceable under

-any particular circumstance, the balance of the section is intended to

-apply and the section as a whole is intended to apply in other

-circumstances.

-

-It is not the purpose of this section to induce you to infringe any

-patents or other property right claims or to contest validity of any

-such claims; this section has the sole purpose of protecting the

-integrity of the free software distribution system, which is

-implemented by public license practices.  Many people have made

-generous contributions to the wide range of software distributed

-through that system in reliance on consistent application of that

-system; it is up to the author/donor to decide if he or she is willing

-to distribute software through any other system and a licensee cannot

-impose that choice.

-

-This section is intended to make thoroughly clear what is believed to

-be a consequence of the rest of this License.

-

-  8. If the distribution and/or use of the Program is restricted in

-certain countries either by patents or by copyrighted interfaces, the

-original copyright holder who places the Program under this License

-may add an explicit geographical distribution limitation excluding

-those countries, so that distribution is permitted only in or among

-countries not thus excluded.  In such case, this License incorporates

-the limitation as if written in the body of this License.

-

-  9. The Free Software Foundation may publish revised and/or new versions

-of the General Public License from time to time.  Such new versions will

-be similar in spirit to the present version, but may differ in detail to

-address new problems or concerns.

-

-Each version is given a distinguishing version number.  If the Program

-specifies a version number of this License which applies to it and "any

-later version", you have the option of following the terms and conditions

-either of that version or of any later version published by the Free

-Software Foundation.  If the Program does not specify a version number of

-this License, you may choose any version ever published by the Free Software

-Foundation.

-

-  10. If you wish to incorporate parts of the Program into other free

-programs whose distribution conditions are different, write to the author

-to ask for permission.  For software which is copyrighted by the Free

-Software Foundation, write to the Free Software Foundation; we sometimes

-make exceptions for this.  Our decision will be guided by the two goals

-of preserving the free status of all derivatives of our free software and

-of promoting the sharing and reuse of software generally.

-

-			    NO WARRANTY

-

-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY

-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN

-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES

-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED

-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF

-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS

-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE

-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,

-REPAIR OR CORRECTION.

-

-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING

-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR

-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,

-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING

-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED

-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY

-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER

-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE

-POSSIBILITY OF SUCH DAMAGES.

-

-		     END OF TERMS AND CONDITIONS

-

-	Appendix: How to Apply These Terms to Your New Programs

-

-  If you develop a new program, and you want it to be of the greatest

-possible use to the public, the best way to achieve this is to make it

-free software which everyone can redistribute and change under these terms.

-

-  To do so, attach the following notices to the program.  It is safest

-to attach them to the start of each source file to most effectively

-convey the exclusion of warranty; and each file should have at least

-the "copyright" line and a pointer to where the full notice is found.

-

-    <one line to give the program's name and a brief idea of what it does.>

-    Copyright (C) 19yy  <name of author>

-

-    This program is free software; you can redistribute it and/or modify

-    it under the terms of the GNU General Public License as published by

-    the Free Software Foundation; either version 2 of the License, or

-    (at your option) any later version.

-

-    This program is distributed in the hope that it will be useful,

-    but WITHOUT ANY WARRANTY; without even the implied warranty of

-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the

-    GNU General Public License for more details.

-

-    You should have received a copy of the GNU General Public License

-    along with this program; if not, write to the Free Software

-    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.

-

-Also add information on how to contact you by electronic and paper mail.

-

-If the program is interactive, make it output a short notice like this

-when it starts in an interactive mode:

-

-    Gnomovision version 69, Copyright (C) 19yy name of author

-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.

-    This is free software, and you are welcome to redistribute it

-    under certain conditions; type `show c' for details.

-

-The hypothetical commands `show w' and `show c' should show the appropriate

-parts of the General Public License.  Of course, the commands you use may

-be called something other than `show w' and `show c'; they could even be

-mouse-clicks or menu items--whatever suits your program.

-

-You should also get your employer (if you work as a programmer) or your

-school, if any, to sign a "copyright disclaimer" for the program, if

-necessary.  Here is a sample; alter the names:

-

-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program

-  `Gnomovision' (which makes passes at compilers) written by James Hacker.

-

-  <signature of Ty Coon>, 1 April 1989

-  Ty Coon, President of Vice

-

-This General Public License does not permit incorporating your program into

-proprietary programs.  If your program is a subroutine library, you may

-consider it more useful to permit linking proprietary applications with the

-library.  If this is what you want to do, use the GNU Library General

-Public License instead of this License.

-\section{Introduction}
-
-The \texttt{invoice} package was conceived in late 2000 when the
-author had to dig through a truly aweful pile of expense bills
-without having a spreadsheet featuring \LaTeXe-compliant output (or
-any spreadsheet, for that purpose) available. After several
-miscalculations with a pocket calculator due to forgotten or
-double entries the idea came up to have \LaTeXe\ do the calculation
-work. As such, the package in its present stage is highly
-specialized with regard to the documents it generates. The
-\texttt{invoice} package is basically a tailor-made solution for a
-consultant who charges fees and claims all sorts of expenses,
-sometimes working on different assignments for the same client.
-
-The author expresses his gratitude to
-Robert Inder,
-Thilo Barth,
-Jacco Kok,
-Fred Donck,
-Jacopo,
-Johann Spies,
-Ian Wormsbecker,
-Vincent Tougait
-and
-Robin Fairbairns
-who contributed ideas, corrections,
-bugfixes and caption translations after the first discussions on
-\texttt{comp.text.tex} and the initial release of \texttt{invoice}.
-
-Given the current capabilities of \texttt{invoice}, it should well
-be possible to extend the capabilities of this package in the future
-or to rewrite it in a generalized fashion.
-
-\section{Software Requirements}
-
-The \texttt{invoice} environment runs under \LaTeXe\ and relies on the
-\texttt{calc.sty} (providing infix arithmetic) and \texttt{realcalc}
-(providing real arithmetic) utilities to do its work which can be found
-at CTAN%
-	\footnote{The \texttt{realcalc} package is found at
-	\texttt{CTAN:macros/generic/realcalc},
-	and \texttt{calc} is found at
-	\texttt{CTAN:macros/latex/required/tools/}.}.
-Compile and read \texttt{00README.tex} for further information if
-you are not sure whether these packages are installed at your site.
-
-\section{The \texttt{invoice} Environment}
-
-Within a given document, invoices are built with the
-\texttt{invoice} environment\footnote{Users of the KOMA-Script 
-	class \texttt{scrlettr.cls} are kindly requested to use
-	\texttt{invoiceenv} instead; see also page~\pageref{koma}.}.
-Figure~\ref{structure} on page~\pageref{structure} shows the
-logical structure of an invoice as well as its basic commands.
-In case a full-fledged invoice stationary is needed, it is recommended
-to use the \texttt{invoice} environment within existing business 
-letters which may have been pre-defined already. The \texttt{invoice}
-package itself does not provide tools for including company logos,
-recipient's addresses, bank account numbers etc. as these are usually
-covered by the various \texttt{letter} classes available for \LaTeXe.

-\end{figure}
-
-Invoices contain one or more projects which in return contain the charged
-items, either fees (plus tax, if applicable) and/or expenses. An
-invoice with one project is announced by saying 
-
-\begin{verbatim}
-\begin{invoice}{<Base Currency>}{<VAT>}
-	\ProjectTitle{...}%
-\end{invoice}
-\end{verbatim}
-
-There is no limit for the number of projects in an invoice, as there
-is no limit for the number of invoices per document.
-
-The \texttt{invoice} environment requires two arguments: 
-\begin{enumerate}
-	\item \texttt{<Base Currency>} is the name of the currency
-		in which the invoice is charged, e.\,g. DM, Euro,
-		US\$, RMB etc.
-	\item \texttt{<VAT>} is the percentage rate of VAT which is charged;
-		in Germany this is currently (winter 2003) 16\%. If
-		no VAT is required, enter a \texttt{0}
-		(\textit{zero}) here. It is neither necessary nor
-		permissible to use a percent sign here. As some
-		countries (e.\,g. France) have fractions of
-		percentages (like 16.9\%), you would in this case
-		enter \verb|16.9| (without any percent sign).
-
-		Setting the VAT rate to \verb-0- produces the side
-		effect that the lines stating the VAT subtotals and
-		totals disappear.
-
-		If it is, however, desired to show the VAT results
-		even if they amount to zero, enter \verb-0.0- instead.
-\end{enumerate}
-
-
-\subsection{Projects}
-
-An invoice contains items which are usually, in the case of e.\,g.
-consultancy fees and related expenses like hotel bills and air
-fares, attributed to a given case or \textit{project}, or
-cost center, or ``Kostenstelle'' (in German).
-
-A project contains any of three different types of charged items:
-\begin{enumerate}
-	\item \textbf{Fees}. A tax can be added, if applicable. Fees 
-		are always charged in the
-			base currency
-		of the invoice.
-	\item \textbf{Local Expenses}. Local expenses are charged in 
-		units of the 
-			base currency
-		of the invoice.
-	\item \textbf{Foreign Expenses}. Foreign expenses are charged in 
-		units of any given foreign currency. Either the
-			base currency
-		equivalent is known (as taken from a credit card
-		billing statement, for example), or, if not, an
-		exchange rate between foreign currency and base
-		currency has to be stated.
-\end{enumerate}
-
-\textbf{Nota bene:} The order of fees and expenses is fixed. Either fees or
-expenses can be omitted, but expenses must be charged \textit{after}
-fees.
-
-
-\section{The First Example: How to Charge Fees}
-
-
-A consultant charges fees per day, hour or any other unit. Usually
-this unit is agreed upon in a contract and there is no further need
-to refer to this unit but by its count. This is done by the
-\verb-\Fee{}{}{}- command:
-
-\begin{verbatim}
-	\Fee{<Contents>}{<Rate/Unit>}{<Count>}
-\end{verbatim}
-
-Let's assume an interim manager
-charges DM 1818.00 a day for 12 working days while
-negotiating a major project, nicknamed \textit{Project Phenix}.
-He also charges DM 2750.00 a day for analysing and negotiating
-the restructuring of the sales division, a work he spent 9 days with.
-
-\subsection{Invoices with VAT}
-
-We further assume that the consultant is required to charge VAT.
-All information above would be entered into the invoice as follows:
-
-\begin{verbatim}
-\begin{invoice}{DM}{16}
-   \ProjectTitle{Project Phenix}%
-       %    Contents                    Rate/Unit   Count
-       \Fee{Some really lengthy and utterly
-       		tedious negotiation}     {1818.00}   {12}
-
-   \ProjectTitle{Sales Restructuring}%
-       %    Contents                    Rate/Unit   Count
-       \Fee{Sales Structure Analysis}   {2750.00}   { 6}
-       \Fee{Negotiation with Agents}    {2750.00}   { 3}
-\end{invoice}
-\end{verbatim}
-
-And here is how the result looks like:
-
-\begin{invoice}{DM}{16}
-	\ProjectTitle{Project Phenix}%
-	\Fee{Some really lengthy and utterly 
-		tedious negotiation}	{1818.00}	{12}
-
-	\ProjectTitle{Sales Restructuring}%
-        \Fee{Sales Structure Analysis}   {2750.00}   { 6}
-        \Fee{Negotiation with Agents}    {2750.00}   { 3}
-\end{invoice}
-
-Hints: If the base currency is to contain a dollar sign (\$), then
-dollar sign must be entered in the form of \verb|\string$|
-or otherwise the command writing the log file data will fail. The
-contents of each fee may be verbose; while the column width is
-limited, text contents longer than the column width wraps over
-several columns, if necessary.
-
-The astute observer will note that a line beginning with ``Subtotal~Fees''
-appeared in the output of the Sales Restructuring Project without explicit
-input to this effect from the user's side. The full grammar of the Fee block
-requires that all fees are closed by a fee subtotal. Internally,
-\texttt{invoice} is defined as a finite state automaton providing
-mechanisms to insert a fee subtotal if logic requires it, and print
-its value if it makes sense to humans, which is the case if there is more
-than one fee.
-
-Note that there is an explicit command \texttt{\char92 STFee} which will
-produce a subtotal of the fees charged so far. This can be used if
-you want to show fee subtotals within the same project.
-
-
-\subsection{Invoices without VAT}
-
-As mentioned above, an invoice may be calculated without any VAT.
-The VAT lines may completely disappear, as in the following
-example:
-\begin{verbatim}
-\begin{invoice}{DM}{0}
-   \ProjectTitle{Project Phenix}%
-       %    Contents                    Rate/Unit   Count
-       \Fee{Some really lengthy and utterly
-       		tedious negotiation}     {1818.00}   {12}
-
-   \ProjectTitle{Sales Restructuring}%
-       %    Contents                    Rate/Unit   Count
-       \Fee{Sales Structure Analysis}   {2750.00}   { 6}
-       \Fee{Negotiation with Agents}    {2750.00}   { 3}
-\end{invoice}
-\end{verbatim}
-
-
-Figure~\ref{invoice_without_VAT} on
-page~\pageref{invoice_without_VAT}
-shows the result.
-
-\begin{figure}[h]
-\begin{invoice}{DM}{0}
-	\ProjectTitle{Project Phenix}%
-	\Fee{Some really lengthy and utterly 
-		tedious negotiation}	{1818.00}	{12}
-
-	\ProjectTitle{Sales Restructuring}%
-        \Fee{Sales Structure Analysis}   {2750.00}   { 6}
-        \Fee{Negotiation with Agents}    {2750.00}   { 3}
-\end{invoice}
-\caption{A complete invoice
-		with fees but no VAT.\label{invoice_without_VAT}}
-\end{figure}
-
-In contrast, if for any reason the VAT subtotals and totals should
-be kept visible despite a \textit{value} of zero, then use a VAT
-value of \verb-0.0- as in the following example:
-\begin{verbatim}
-\begin{invoice}{DM}{0.0}
-   \ProjectTitle{Project Phenix}%
-       %    Contents                    Rate/Unit   Count
-       \Fee{Some really lengthy and utterly
-       		tedious negotiation}     {1818.00}   {12}
-
-   \ProjectTitle{Sales Restructuring}%
-       %    Contents                    Rate/Unit   Count
-       \Fee{Sales Structure Analysis}   {2750.00}   { 6}
-       \Fee{Negotiation with Agents}    {2750.00}   { 3}
-\end{invoice}
-\end{verbatim}
-
-
-Figure~\ref{invoice_with_zero_VAT} on

-\end{invoice}
-\caption{A complete invoice
-		with fees but zero VAT.\label{invoice_with_zero_VAT}}
-\end{figure}
-
-
-\section{The Second Example: How to Claim Expenses}
-
-Expenses can be charged in base currency or in any foreign currency.
-The base currency's name should be announced once at the beginning
-of the invoice.
-
-\subsection{Expenses in Base Currency}
-
-The shape of an expense item in base currency is simple:
-
-\begin{verbatim}
-\EBC{<Contents>}                {<Amount>}
-\end{verbatim}
-
-Both fields contain mandatory arguments:
-
-\begin{enumerate}
-	\item \texttt{<Contents>} contains a description of the
-		charged item, e.\,g. ``Hotel'', ``Airport Tax'' or
-		whatever.
-	\item \texttt{<Amount>} contains the amount in base currency
-		units.
-\end{enumerate}
-
-
-\subsection{Expenses in Foreign Currency}
-
-Charging an expense in foreign currency is only slightly more
-complicated. The command is:
-
-\begin{verbatim}
-\EFC{<Contents>}
-    {<Foreign Currency>}{<Amount>}
-    {<Conversion Rate>}{<Base Currency Result>}
-\end{verbatim}
-
-Arguments to the five fields are partially mandatory, partially optional:
-\begin{enumerate}
-	\item \texttt{<Contents>} contains a description of the
-		charged item, e.\,g. ``Hotel'', ``Airport Tax'' or
-		whatever.
-
-	\item \texttt{<Foreign Currency>} contains the name of the
-		foreign currency.
-
-	\item \texttt{<Amount>} contains the amount in foreign currency
-		units.
-	
-	\item \texttt{<Conversion Rate>} contains the factor by
-		which the foreign currency amount has to be
-		multiplied in order to achieve the base currency
-		result. If the base currency result is stated,
-		then, and only then, the Conversion Rate can be
-		omitted.
-	
-	\item \texttt{<Base Currency Result>} contains an optional
-		amount in base currency units. Credit card billing
-		statements show this amount which usually contains
-		certain service charges of the credit card issuer;
-		the base currency result is thus the true amount of
-		money to be charged. If a \texttt{<Conversion Rate>}
-		is given, stating a base currency result becomes
-		optional. This is usually applied for expenses made
-		with cash money.
-\end{enumerate}
-
-
-Since some of the arguments given to \verb-\EFC- are optional,
-there are basically two different forms of using this command.
-With the variant
-
-\begin{verbatim}
-\EFC{<Contents>}{<Foreign Currency>}{<Amount>}
-        {<Conversion Rate>}               % Conversion rate
-        {}                                % Base currency empty!
-\end{verbatim}
-
-(amount in foreign currency given, as well as exchange rate stated),
-the command will automatically calculate the resulting amount in
-base currency.
-
-\begin{verbatim}
-\EFC{<Contents>}
-        {<Foreign Currency>}{<Amount>}
-        {}                                % Conversion rate empty!
-        {<Base Currency Result>}          % Base currency
-\end{verbatim}
-
-If, however, the exchange rate is omitted and the target amount in
-base currency is given, then this value is taken directly. Stating
-the resulting amount overrides the internal calculation mechanism.
-Examples are given below. We use our interim manager's invoice
-again, assuming this time that she spent working on Project Phenix 
-12 days in her home country while the Sales Restructuring effort
-took her to Hong Kong. The taxi bills are paid in cash, hence she
-enters the (fictive) conversion rate, whereas the hotel is paid by
-credit card. She can then take the final amount from her credit card
-billing statement; an example input would look as follows:
-
-\begin{verbatim}
-\begin{invoice}{DM}{16}
-   \ProjectTitle{Project Phenix}%
-       %    Contents                    Rate/Unit   Count
-       \Fee{Negotiation}                {1818.00}   {12}
-       %
-       %    Contents                    Amount
-       \EBC{Hotel, 12 nights}           {2400.00}
-
-   \ProjectTitle{Sales Restructuring}%
-       %    Contents                    Rate/Unit   Count
-       \Fee{Sales Structure Analysis}   {2750.00}   { 6}
-       \Fee{Negotiation with Agents}    {2750.00}   { 3}
-       %
-       %    Contents              Currency  Amount  Conv.Rate Result
-       \EFC{Taxi Airport -- Hotel} {HK\$}  {325.00} {0.2354}   {}
-       \EFC{Hotel, 9 nights}       {HK\$}  {9180.00}   {}    {2111.40}
-\end{invoice}
-\end{verbatim}
-
-Figure~\ref{full_invoice} on
-page~\pageref{full_invoice}
-shows the result.
-
-\begin{figure}[h]
-\begin{invoice}{DM}{16}
-	\ProjectTitle{Project Phenix}%
-	\Fee{Negotiation}		{1818.00}	{12}
-       %
-       %    Contents                    Amount
-       \EBC{Hotel, 12 nights}		{2400.00}
-
-	\ProjectTitle{Sales Restructuring}%
-       \Fee{Sales Structure Analysis}   {2750.00}   { 6}
-       \Fee{Negotiation with Agents}    {2750.00}   { 3}
-       %
-       %    Contents              Currency  Amount  Conv.Rate Result
-       \EFC{Taxi Airport -- Hotel} {HK\$}  {325.00} {0.2354}   {}
-       \EFC{Hotel, 9 nights}       {HK\$}  {9180.00}   {} {2111.40}
-\end{invoice}
-\caption{A complete invoice with fees and expenses.\label{full_invoice}}
-\end{figure}
-
-Again, a subtotal of the expenses appears only if there is more than
-one expense item in a project.
-
-
-\subsection{Hidden Expense Details}
-
-Occasionally it may be desirable to list only the total of expenses
-incurred, while hiding the structure of expenses. In such a case,
-the expense commands can be modified by attaching an \verb|i| to
-their names (as in \textit{invisible}).
-
-A hidden expense in base currency is thus declared as:
-
-\begin{verbatim}
-\EBCi{<Contents>}                {<Amount>}
-\end{verbatim}
-
-A hidden expense in foreign currency is declared as:
-
-\begin{verbatim}
-\EFCi{<Contents>}
-     {<Foreign Currency>}{<Amount>}
-     {<Conversion Rate>}{<Base Currency Result>}
-\end{verbatim}
-
-Both commands accept and require exactly the same arguments as their
-visible counterparts. The expenses will be added to the expense subtotals
-and the invoice total in the same way as if they were visible. If there
-is no visible expense stated at all it may be useful to have at least 
-a line with the expense subtotal appear; this is done by the \verb|STExpenses|
-command, as shown in the following example:
-
-\begin{verbatim}
-\begin{invoice}{DM}{16}
-   \ProjectTitle{Project Phenix}%
-       %    Contents                    Rate/Unit   Count
-       \Fee{Negotiation}                {1818.00}   {12}
-       %
-       %    Contents                    Amount
-       \EBCi{Hotel, 12 nights}           {2400.00}
-       %
-       \STExpenses
-
-   \ProjectTitle{Sales Restructuring}%
-       %    Contents                    Rate/Unit   Count
-       \Fee{Sales Structure Analysis}   {2750.00}   { 6}
-       \Fee{Negotiation with Agents}    {2750.00}   { 3}
-       %
-       %    Contents              Currency  Amount  Conv.Rate Result
-       \EFCi{Taxi Airport -- Hotel} {HK\$}  {325.00} {0.2354}   {}
-       \EFCi{Hotel, 9 nights}       {HK\$}  {9180.00}   {}    {2111.40}
-       \STExpenses
-\end{invoice}
-\end{verbatim}

-\section{Deduction of Discounts and Downpayments}
-
-Finally, it may be possible that previous downpayments etc. have to 
-be considered for the invoice total. An optional discount line
-can state the item and deduct the amount from the invoice total.
-Deductions are always stated in base currency. They follow the following
-syntax:
-
-
-\begin{verbatim}
-\Discount{<Contents>}     {<Amount>}
-\end{verbatim}
-
-Both fields contain mandatory arguments:
-
-\begin{enumerate}
-	\item \texttt{<Contents>} contains a description of the
-		discount item, e.\,g. ``Downpayment'', ``Tickets for 
-		private use'' or whatever.
-	\item \texttt{<Amount>} contains the amount in base currency
-		units.
-\end{enumerate}
-
-Figure~\ref{full_and_discounted_invoice} on
-page~\pageref{full_and_discounted_invoice}
-shows the result.

-		expenses and a deduction.\label{full_and_discounted_invoice}}
-\end{figure}
-
-\section{Postprocessing}
-
-In order to allow the further processing of
-\texttt{invoice}-generated data, the log file contains the totals of
-fees, expenses and taxes in the form of \verb-key:value- pairs. This
-information appears also on the terminal while \LaTeXe\ runs. Please
-note that the key appearing in the log file is expressed in the same
-language as that of the master document.
-
-\section{Document Language}
-
-All column headers appearing in \texttt{invoice} can be redefined in
-order to match the language of the master document. E.\,g., headings
-like ``Total'' will automatically appear as ``Gesamtsumme'' if the
-document language is set to German (either via \texttt{babel} or
-\verb-\usepackage{german}-).
-
-Please observe that the \texttt{invoice} package must be called {\em
-after} the document language has been selected.
-
-This is correct:
-
-\begin{verbatim}
-\documentclass[10pt]{ltxdoc}
-\usepackage{german}
-\usepackage{invoice} % labels will now appear in German!
-\end{verbatim}
-
-This will not work:
-
-\begin{verbatim}
-\documentclass[10pt]{ltxdoc}
-\usepackage{invoice}
-\usepackage{german} % labels will still appear in English!
-\end{verbatim}
-
-
-\subsection{Specifying the Desired Language}
-
-It is also possible to ignore the global language settings and select
-a language local to the \texttt{invoice} package by specifying the
-desired language as an option:
-
-\begin{verbatim}
-\documentclass[10pt]{ltxdoc}
-\usepackage[german]{invoice} % labels in German, rest 
-                             % of document in English
-\end{verbatim}
-
-This is useful whenever the desired language is not provided by the
-installation base where \texttt{invoice} is executed.
-
-\subsection{Adding Labels in a New Language}
-
-At present, column labels produced by \texttt{invoice} can appear
-in six languages: Afrikaans, Dutch, English, French, German and Italian.
-Other languages can be added easily by editing the file
-\verb-invoice.def-. Language-dependent definitions are contained in
-the \verb-\if-clause. Extending the file is simple: 
-
-\begin{enumerate}
-	\item Copy the labels template to the end of the file.
-	\item Remove the comments (\verb-%-) in column 1.
-	\item Fill each label definition with the appropriate
-		foreign language translation.
-	\item Put the correct internal name of the foreign language
-		into the condition expression of the \verb-\ifx--
-		and \verb-\ifnum--clauses.
-\end{enumerate}
-
-\begin{sloppypar}
-Whenever you create your own foreign language extension please kindly
-consider sending your modified \verb-invoice.def- file to the author
-(at \verb+corff@zedat.fu-berlin.de+ or \verb+oliver.corff@email.de+)
-so that it can be included in the next update. Future users can then
-share your work.
-\end{sloppypar}
-
-\section{Bugs}
-
-Certainly there are bugs. After all, this is not Moon, but Earth
-(where life is supposed to exist, as opposed to Moon). The author 
-has not conducted extensive tests on the algebraic functions, and
-there may be rounding and truncating errors.
-
-The author considers it a bug that the decimal point cannot be
-replaced by a comma at present, while entering dollar signs
-requires the \verb|\string$| notation.
-
-Spurious spaces may distort the table layout. It is especially
-recommended to close all \verb"\ProjectTitle{...}%" lines with a
-percent mark, as shown. If the percent mark is omitted, the first
-column header is not properly aligned to the left.
-
-Breaking long invoice statements with many projects over several
-pages results in many orphans and widows.
-
-\subsection{\label{koma}Compatibility with KOMA-Script}
-
-Unfortunately, when first writing this package the author was not aware
-of the KOMA-Script classes, notably the class \texttt{scrlettr.cls}
-which defines its own \verb-\invoice{#1}- command, albeit with completely
-different scope, usage and syntax. KOMA-Script's \verb-\invoice{#1}- command
-accepts a number and prints ``Invoice no. \#1'' in a letter 
-opening. Now that the names of the \texttt{invoice} package and
-environment have stuck it is easier to think of a workaround than to
-conceive a new name. Therefore, If the class \texttt{scrlettr.cls} is
-used, the environment \texttt{invoice} is automatically renamed to
-\texttt{invoiceenv}. Writing 
-
-\begin{verbatim}
-\documentclass[10pt]{scrlettr}
-\usepackage{invoice}
-\begin{invoice}{DM}{16}
-...
-...
-\end{verbatim}
-
-will result in an error message. Say \verb-\begin{invoiceenv}{DM}{16}-
-instead.  KOMA-Script's own \verb-\invoice{#1}- command is renamed to
-\verb-\invoiceno{#1}-, while \verb-\invoice{#1}- now generates an 
-error message reminding KOMA-Script users to apply the renamed
-commands.
-
-\section{Desiderata}
-
-The \verb-invoice- package is far from complete. Future expansions
-should aim at making the package more flexible. How taxes are
-treated, etc., is at present a rather particular arrangement
-suitable for the author's immediate needs, but a more general
-solution can be designed as soon as more users reflect their needs
-to the author.
