+zmac (Z-80 cross assembler)
+
+zmac is a Z-80 macro cross-assembler. It has all the features you'd
+expect. It assembles the specified input file (with a '.z' extension
+if there is no pre-existing extension and the file as given doesn't
+exist) and produces program output in many different formats. It also
+produces a nicely-formatted listing of the machine code and cycle
+counts alongside the source in a ".lst" file. Undocumented Z-80
+instructions are supported as well as 8080 and Z-180 (aka HD64180).
+
+zmac strives to be a powerful assembler with expressions familiar to C
+programmers while providing good backward compatibility with original
+assemblers such as Edtasm, MRAS and Macro-80.
+
+Also included in the package is ld80, a linker which is mostly
+compatible with the Microsoft L80 linker for CP/M and other Z-80 OSes.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.

+.SH DESCRIPTION
+.sp
+zmac is a Z\-80 macro cross\-assembler. It has all the features you\(aqd
+expect. It assembles the specified input file (with a \(aq.z\(aq extension
+if there is no pre\-existing extension and the file as given doesn\(aqt
+exist) and produces program output in many different formats. It also
+produces a nicely\-formatted listing of the machine code and cycle
+counts alongside the source in a ".lst" file.
+.sp
+To reduce clutter and command line option usage, by default all zmac
+output is put into an (auto\-created) zout subdirectory. For file.z
+the listing will be in zout/file.lst, the TRS\-80 executable format
+in zout/file.cmd and so on. For more friendly usage in make files
+and integrated development environments the \-o, \-\-oo, \-\-xo and \-\-xd
+options may be used to select specific output file formats and where
+they are written.
+.sp
+Undocumented Z\-80 instructions are supported as well as 8080 and Z\-180
+(aka HD64180).
+.sp
+zmac strives to be a powerful assembler with expressions familiar to C
+programmers while providing good backward compatibility with original
+assemblers such as Edtasm, MRAS and Macro\-80.
+.sp
+This man page only documents the command\-line options. The full documentation can be found here:
+/usr/doc/zmac\-20221018_0.7/zmac.html
+.SH OPTIONS
+.sp
+Space\-separated arguments in the ZMAC_ARGS environment variable are added to the
+end of the command line.
+.INDENT 0.0
+.TP
+.B  \-\-help
+Display a list of options and a terse description of what the
+options do.
+.TP
+.B  \-\-version
+Print zmac version name.
+.TP
+.B  \-\-mras
+MRAS compatibility mode. Any ? in a label will be expanded to
+the current module identifier as set by *mod. Operator
+precedence and results are changed.
+.TP
+.BI \-\-od \ dir
+Place output files in dir instead of the default "zout"
+subdirectory. Creates dir if necessary.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-\-oo hex,cmd
+Output only the the file types by suffix. Multiple \-\-oo
+arguments may be used. "\-\-oo lst,cas" is equivalent to "\-\-oo
+lst \-\-oo cas". See "Output Formats" for a list of output types
+by suffix.
+.TP
+.B \-\-xo tap,wav
+Do not output the file type types listed by suffix.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B  \-\-dri
+Enable compatibility with Digital Research (CP/M) assemblers:
+Ignores dollar signs in constants and symbols. Silences a
+warning when using Z80.LIB. Allows the use of \(aq*\(aq in first
+column for comment lines. Accepts $\-MACRO directives.
+.TP
+.B  \-\-nmnv
+Do not interpret Z\-80 or 8080 mnemonics as values in
+expressions.
+.TP
+.B  \-\-rel
+Output ".rel" (relocatable object file) format only. Exported
+symbols are truncated to length 6.
+.TP
+.B  \-\-rel7
+Output ".rel" (relocatable object file) format only. Exported
+symbols are truncated to length 7.
+.TP
+.B  \-\-zmac
+zmac compatibility mode. defl labels are undefined after each
+pass. Quotes and double quotes are stripped from macro
+arguments before expansion. $ is ignored in identifiers
+allowing foo$bar to construct identifiers in macro expansions.
+Use \(ga (backquote) instead in normal mode. Labels starting with
+"." are temporary and are reset whenever a non\-temporary label
+is defined (thus they may be reused). Labels starting with "_"
+are local to their file thus avoid multiple definition when
+brought in with include.
+.TP
+.B  \-\-z180
+Use Z\-180 timings and extended instructions. Undocumented Z\-80
+instructions will generate errors as the Z\-180 (or H64810) does
+not support them. Equivalent to .z180 pseudo\-op.
+.TP
+.B  \-\-dep
+Print all files read by include, incbin and import.
+.TP
+.B  \-\-doc
+Print full documentation in HTML format to standard output.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-Pk=number
+Set @@k to the given numeric value before assembly. Up to 10
+parameters can be set from 0 though 9. \-Pk is shorthand for
+\-Pk=\-1. For example, P4=$123 effectively puts @@4 equ $123 at
+the top of the first file.
+.UNINDENT
+.INDENT 0.0
+.TP
+.BI \-D\fB symbol
+Define symbol to be 1 before assembly.
+.TP
+.B  \-\-fcal
+Always treat an indentifier in the first column as a label.
+zmac uses various heuristics in the case of ambiguity when a
+label does not have a colon. This option turns heuristics off.
+.TP
+.B  \-8
+Accept 8080 mnemonics preferentially and use 8080 instruction
+timings. Equivalent to .8080 pseudo\-op.
+.TP
+.B  \-b
+Don\(aqt generate any machine code output at all.
+.TP
+.B  \-c
+Don\(aqt display cycle counts in the listing.
+.TP
+.B  \-e
+Omit the "error report" section in the listing.
+.TP
+.B  \-f
+List instructions not assembled due to "if" expressions being
+false. (Normally these are not shown in the listing.)
+.TP
+.B  \-g
+List only the first line of equivalent hex for a source line.
+.TP
+.B  \-h
+Display a list of options and a terse description of what the
+options do. (same as \-\-help)
+.TP
+.B  \-i
+Don\(aqt list files included with include, read or import.
+.TP
+.BI \-I \ dir
+Add dir to the end of the include file search path.

+.B  \-J
+Error if an absolute jump could be replaced with a relative
+jump.
+.TP
+.B  \-l
+List to standard output.
+.TP
+.B  \-L
+Generate listing no matter what. Overrides any conflicting
+options.
+.TP
+.B  \-m
+List macro expansions.
+.TP
+.B  \-n
+Omit line numbers from listing.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B \-o filename.cmd
+Output only the named file. Multiple "\-o" options can be used
+to name a set of different files.
+.UNINDENT
+.INDENT 0.0
+.TP
+.B  \-p
+Use a few linefeeds for page break in listing rather than ^L.
+.TP
+.B  \-P
+Output listing for a printer with headers, multiple symbols per
+column, etc.
+.TP
+.B  \-s
+Omit the symbol table from the listing.

+DESCRIPTION
+===========
+
+zmac is a Z-80 macro cross-assembler. It has all the features you'd
+expect. It assembles the specified input file (with a '.z' extension
+if there is no pre-existing extension and the file as given doesn't
+exist) and produces program output in many different formats. It also
+produces a nicely-formatted listing of the machine code and cycle
+counts alongside the source in a ".lst" file.
+
+To reduce clutter and command line option usage, by default all zmac
+output is put into an (auto-created) zout subdirectory. For file.z
+the listing will be in zout/file.lst, the TRS-80 executable format
+in zout/file.cmd and so on. For more friendly usage in make files
+and integrated development environments the -o, --oo, --xo and --xd
+options may be used to select specific output file formats and where
+they are written.
+
+Undocumented Z-80 instructions are supported as well as 8080 and Z-180
+(aka HD64180).
+
+zmac strives to be a powerful assembler with expressions familiar to C
+programmers while providing good backward compatibility with original
+assemblers such as Edtasm, MRAS and Macro-80.
+
+This man page only documents the command-line options. The full documentation can be found here:
+/usr/doc/zmac-|version|/zmac.html
+
+OPTIONS
+=======
+
+Space-separated arguments in the ZMAC_ARGS environment variable are added to the
+end of the command line.
+
+
+--help           Display a list of options and a terse description of what the
+                 options do.
+
+--version        Print zmac version name.
+
+--mras           MRAS compatibility mode. Any ? in a label will be expanded to
+                 the current module identifier as set by \*mod. Operator
+                 precedence and results are changed.
+
+--od dir         Place output files in dir instead of the default "zout"
+                 subdirectory. Creates dir if necessary.
+
+--oo hex,cmd
+                 Output only the the file types by suffix. Multiple --oo
+                 arguments may be used. "--oo lst,cas" is equivalent to "--oo
+                 lst --oo cas". See "Output Formats" for a list of output types
+                 by suffix.
+
+--xo tap,wav
+                 Do not output the file type types listed by suffix.
+
+--dri            Enable compatibility with Digital Research (CP/M) assemblers:
+                 Ignores dollar signs in constants and symbols. Silences a
+                 warning when using Z80.LIB. Allows the use of '*' in first
+                 column for comment lines. Accepts $-MACRO directives.
+
+--nmnv           Do not interpret Z-80 or 8080 mnemonics as values in
+                 expressions.
+
+--rel            Output ".rel" (relocatable object file) format only. Exported
+                 symbols are truncated to length 6.
+
+--rel7           Output ".rel" (relocatable object file) format only. Exported
+                 symbols are truncated to length 7.
+
+--zmac           zmac compatibility mode. defl labels are undefined after each
+                 pass. Quotes and double quotes are stripped from macro
+                 arguments before expansion. $ is ignored in identifiers
+                 allowing foo$bar to construct identifiers in macro expansions.
+                 Use ` (backquote) instead in normal mode. Labels starting with
+                 "." are temporary and are reset whenever a non-temporary label
+                 is defined (thus they may be reused). Labels starting with "_"
+                 are local to their file thus avoid multiple definition when
+                 brought in with include.
+
+--z180           Use Z-180 timings and extended instructions. Undocumented Z-80
+                 instructions will generate errors as the Z-180 (or H64810) does
+                 not support them. Equivalent to .z180 pseudo-op.
+
+--dep            Print all files read by include, incbin and import.
+
+--doc            Print full documentation in HTML format to standard output.
+
+-Pk=number
+                 Set @@k to the given numeric value before assembly. Up to 10
+                 parameters can be set from 0 though 9. -Pk is shorthand for
+                 -Pk=-1. For example, P4=$123 effectively puts @@4 equ $123 at
+                 the top of the first file.
+
+-Dsymbol         Define symbol to be 1 before assembly.
+
+--fcal           Always treat an indentifier in the first column as a label.
+                 zmac uses various heuristics in the case of ambiguity when a
+                 label does not have a colon. This option turns heuristics off.
+
+-8               Accept 8080 mnemonics preferentially and use 8080 instruction
+                 timings. Equivalent to .8080 pseudo-op.
+
+-b               Don't generate any machine code output at all.

+-e               Omit the "error report" section in the listing.
+
+-f               List instructions not assembled due to "if" expressions being
+                 false. (Normally these are not shown in the listing.)
+
+-g               List only the first line of equivalent hex for a source line.
+
+-h               Display a list of options and a terse description of what the
+                 options do. (same as --help)
+
+-i               Don't list files included with include, read or import.
+
+-I dir           Add dir to the end of the include file search path.
+
+-j               Promote relative jumps and DJNZ to absolute equivalents as
+                 needed.
+
+-J               Error if an absolute jump could be replaced with a relative
+                 jump.
+
+-l               List to standard output.
+
+-L               Generate listing no matter what. Overrides any conflicting

+-m               List macro expansions.
+
+-n               Omit line numbers from listing.
+
+-o filename.cmd
+                 Output only the named file. Multiple "-o" options can be used
+                 to name a set of different files.
+
+-p               Use a few linefeeds for page break in listing rather than ^L.
+
+-P               Output listing for a printer with headers, multiple symbols per
+                 column, etc.
+
+-s               Omit the symbol table from the listing.
+
+-t               Only output number of errors instead list of each one.
+
+-z               Accept Z-80 mnemonics preferentially and use Z-80 instruction
+                 timings. Equivalent to .z80 pseudo-op.
