versions v0.*. In the future, this file won't be changed any
more.
* ChangeLog: New file. It is this file. It displays the history
of `glilypond' versions v1.* or later.
* glilypond.pl: New main Perl file written from
`groff_lilypond.pl' in a totally different way. It is split now
into 4 Perl files.
* args.pl: New Perl file. It handles the command line options for
a run of `glilypond.pl'.

+In order to have this program installed by `make', the creation of a
+libdir (library directory) must be programmed in some system files.
+The following actions must be taken:
+
+1) <groff_src_dir>/m4/groff.m4:
+Add `AC_DEFUN([GROFF_GROFFERDIR_DEFAULT])'.
+
+2) <groff_src_dir>/configure.ac:

+
+3) <groff_src_dir>/Makefile.in:
+Add several informations of `glilypond_dir'
+
+With that, the program `autoconf' can be run in order to update the
+configure files and Makefile's.
+
+Now `$glilypond_dir' can be used as libdir.

+The program

+.
+Then the

+.
+.

+.\" --------------------------------------------------------------------
+.
+.TP
+.OP+ -e | --eps_dir directory_name
+Normally all
+.FONT CI EPS
+files are sent to the temporary directory.
+.
+With this option, you can generate your own directory, in which all useful
+.FONT CI EPS
+files are send.
+.
+So at last, the temporary directory can be removed.
+.
+.
+.TP
+.OP+ -p | --prefix begin_of_name
+Normally all temporary files get names that start with the

+prefix.
+.
+With this option, you can freely change this prefix.
+.
+.
+.TP
+.OP+ -k | --keep_all
+Normally all temporary files without the

+files are deleted.
+.
+With this opton, all generated files either by the
+.FONT CB lilypond
+program or other format transposers are kept.
+.
+.
+.TP
+.OP+ -t | --temp_dir dir
+With this option, you call a directory that is the base for the
+temporary directory.
+.
+This directory name is used as is without any extensions.
+.
+If this directory does not exist it is be created.
+.
+The temporary directory is created by Perl's security operations
+directly under this directory.
+.
+In this temporary directory, the temporary files are stored.

+.
+With this option, that can be changed, such that the output is stored

+.IR file_name .
+.
+.
+.TP
+.OP+ -V | --verbose
+A lot more of information is sent to STDERR.
+.
+.
+.\" --------------------------------------------------------------------
+.SS "Short Option Collections"
+.\" --------------------------------------------------------------------
+.
+The argument handling of options
+.
+.
+.P
+.FONT CI "Short options"
+are arguments that start with a single dash
+.FONT CB \- R .
+.
+Such an argument can consist of arbitrary many options without option
+argument, composed as a collection of option characters following the
+single dash.
+.
+.
+.P
+Such a collection can be terminated by an option character that
+expects an option argument.
+.
+If this option character is not the last character of the argument,
+the follwing final part of the argument is the option argument.
+.
+If it is the last character of the argument, the next argument is
+taken as the option argument.
+.
+.
+.P
+This is the standard for
+.FONT CI POSIX
+and
+.FONT CI GNU
+option management.
+.
+.
+.P
+For example,
+.
+.TP
+.FONT CB \-kVesome_dir
+is a collection of the short options
+.FONT CB \-k
+and
+.FONT CB \-V
+without option argument, followed by the short option
+.FONT \-e
+with option argument that is the following part of the argument
+.FONT CB some_dir R .
+.
+So this argument could also be written as several arguments
+.FONT CB "\-k \-V \-e some_dir" R .
+.
+.
+.\" --------------------------------------------------------------------
+.SS "Handling of Long Options"
+.\" --------------------------------------------------------------------
+.
+Arguments that start with a double dash
+.FONT CB \-\-
+are so-called
+.FONT CI "long options" R .
+.
+Each double dash argument can only have a single long option.
+.
+.
+.P
+.FONT CI "Long options"
+have or have not an option argument.
+.
+An option argument can be the next argument or can be appended with an
+equal sign
+.FONT CB =
+to the same argument as the long option.
+.
+.
+.TP
+.FONT CB \-\-help
+is a long option without an option argument.
+.
+.TP
+.FONT CB "\-\-eps_dir some_dir"
+.TQ
+.FONT CB "\-\-eps_dir=some_dir"
+is the long option
+.FONT CB "\-\-eps_dir
+with the option argument
+.FONT CB some_dir R .
+.
+.
+.P
+Moreover the program allows abbreviations of long options, as much as
+possible.
+.
+.
+.P
+The
+.FONT CI "long option"
+.FONT CB \-\-keep_all
+can be abbreviated from
+.FONT CB \-\-keep_al
+up to
+.FONT CB \-\-k
+because the program does not have another
+.FONT CI "long option"
+whose name starts with the character
+.FONT CB k R .
+.
+.
+.P
+On the other hand, the option
+.FONT \-\-version
+cannot be abbreviated further than
+.FONT \-\-vers
+because there is also the
+.FONT CI "long option " CB \-\-verbose
+that can be abbreviated up to
+.FONT \-\-verb R .
+.
+.
+.P
+An option argument can also be appended to an abbreviation.
+.
+So is
+.FONT CB \-\-e=some_dir
+the same as
+.FONT CB "\-\-eps_dir some_dir" R .
+.
+.
+.P
+Moreover the program allows an arbitrary usage of upper and lower case
+in the option name.
+.
+This is
+.FONT CI Perl
+style.
+.
+.
+.P
+For example, the
+.FONT CI long option
+.FONT CB \-\-keep_all
+can as well be written as
+.FONT CB \-\-Keep_All
+or even as an abbreviation like
+.FONT CB \-\-KeE R .
+.
+.
+.\" --------------------------------------------------------------------
+.SH FILESPEC ARGUMENTS
+.\" --------------------------------------------------------------------
+.
+An argument that is not an option or an option argument is called a
+.FONT CI filespec
+argument.
+.
+.
+.P
+Without any
+.I filespec
+argument,
+.FONT CI "standard input"
+is read.
+.
+.
+.P
+Each
+.I filespec
+argument must either be the name of a readable file or a dash
+.FONT CB -
+for
+.FONT CI "standard input" R .
+.
+Each input must be written in the
+.FONT CI roff
+or
+.FONT CI groff
+language and can include
+.FONT CI lilypond
+parts.
+.
+.
+.P
+Normally arguments starting with a dash
+.FONT CB \-
+are interpreted as an option.
+.
+But if you use an argument that consists only of a doubled dash
+.FONT CB \-\- R ,
+all following arguments are taken as
+.FONT CI filespec
+argument, even if such an argument starts with a dash.
+.
+This is handled according to the
+.FONT CI GNU
+standard.
+.

+.
+A
+.FONT CI lilypond
+part within a structure written in the

+.FONT CB ".lilypond start"

+.FONT CB ".lilypond end"
+.EE
+.
+.
+.P
+A
+.FONT CI groff

+.
+.
+.P
+When processing such a

+we say that the

+.
+.
+.\" --------------------------------------------------------------------
+.SS "Inclusion of ly-Files"

+.
+An additional command line for file inclusion of

+.
+For each such

+code.
+.
+Arbitrarily many of these commands can be included in the
+.FONT CI groff
+input.
+.
+.
+.P
+These include commands can only be used outside the
+.FONT CI lilypond
+parts.
+.
+Within the
+.FONT CI "lilypond mode" R ,
+this inclusion is not possible.
+.
+So
+.FONT CB ".lilypond include"
+may not be used in
+.FONT CI "lilypond mode" R ,
+i.e. between
+.FONT CB ".lilypond start"
+and
+.FONT CB ".lilypond end" R .
+.
+.
+These included
+.FONT CI ly R -files
+are also transformed into
+.FONT CI EPS
+files.
+.
+.
+.\" --------------------------------------------------------------------
+.SH "GENERATED FILES"
+.\" --------------------------------------------------------------------
+.
+By the transformation process of
+.FONT CI lilypond
+parts into
+.FONT CI EPS
+files, there are many files generated.
+.
+By default, these files are regarded as temporary files and as such
+stored in a temporary directory.
+.
+.
+.P
+This process can be changed by command line options.
+.
+.
+.\" --------------------------------------------------------------------
+.SS "Command Line Options for Directories"
+.\" --------------------------------------------------------------------
+.
+The temporary directory for this program is either created
+automatically or can be named by the option
+.OP+ -t | --temp_dir dir .
+.
+.
+.P
+Moreover, the
+.FONT CI EPS
+files that are later on referred by
+.FONT CB .PSPIC
+command in the final
+.FONT CI groff
+output can be stored in a different directory that can be set by the
+command line option
+.OP+ -e | --eps_dir directory_name .
+.
+With this option, the temporary directory can be removed completely at
+the end of the program.
+.
+.
+.P
+The beginning of the names of the temporary files can be set by the
+command line option
+.OP+ -p | --prefix begin_of_name .
+.
+.
+.P
+All of the temporary files except the
+.FONT CI EPS
+files are deleted finally.
+.
+This can be changed by setting the command line option
+.OP+ -k | --keep_files
+.
+With this, all temporary files and directories are kept, not deleted.
+.
+.
+.P
+These
+.FONT CI EPS
+files are stored in a temporary or
+.FONT CI EPS
+directory.
+.
+But they cannot be deleted by the transformation process because they
+are needed for the display which can take a long time.

+.
+This mode is the default.
+.
+It can also be chosen by the option
+.FONT CB --ly2eps R .
+.
+.
+.P
+In this mode, the
+.FONT CB .ly
+files are transformed by the
+.FONT CB lilypond

+files, using
+.EX

+.
+The output

+.P
+There are many

+files created.
+.
+One having the complete transformed
+.FONT CB ly

+.FONT I file\-name CB .eps R .
+.
+.
+.P
+Moreover there are
+.FONT CI EPS
+files for each page, named
+.FONT I file\-name CB \- I digit CB .eps R .
+.
+.
+.P
+The last step to be done is replacing all
+.FONT CI lilypond
+parts by the collection of the corresponding
+.FONT CI EPS

+.
+This is done by

+.
+.
+.P
+In this mode, the
+.FONT CB .ly

+.BR lilypond (1)
+program into
+.FONT CI pdf
+files, using
+.EX

+.
+The

+must be provided without the extension
+.FONT CB .pdf R .
+.
+By this process, a file
+.FONT CI file-name CB .pdf
+is generated.
+.
+.
+.P
+The next step is to transform these
+.FONT CI PDF
+files into a
+.FONT CI PS
+file.
+.
+This is done by the
+.BR pdf2ps (1)
+program using
+.EX
+.FONT R "$ " CB "pdf2ps " CI file-name CB ".pdf " CI file-name CB ".ps"
+.EE
+.
+.
+The next step creates an

+.
+This is done by the
+.BR ps2eps (1)
+program using
+.EX
+.FONT R "$ " CB "ps2eps " CI file-name CB ".ps"
+.EE
+.
+.
+.P
+By that, a file

+is created for each
