+ovcc (CoCo 3 emulator)
+
+ovcc is the portable and Open Virtual Color Computer, a cross-platform
+port of the Windows-only VCC emulator.
+
+ovcc is an accurate emulation of a "stock" Tandy Color Computer 3 (aka
+CoCo 3), just as you would have bought in a Radio Shack store or Tandy
+Computer Center in 1986-1992.
+
+The package includes the ROM images needed for all the emulated
+hardware.

+.SH NAME
+ovcc \- TRS-80 CoCo 3 emulator
+.\" RST source for ovcc(1) man page. Convert with:
+.
+.\" rst2man.py ovcc.rst > ovcc.6
+.
+.SH SYNOPSIS
+.sp
+\fBovcc\fP [\fIquickload\-file\fP]
+.SH DESCRIPTION
+.sp
+\fBovcc\fP is "the portable and open Virtual Color Computer", an emulator
+for the TRS\-80 Color Computer 3.
+.sp
+This man page documents \fBovcc\fP as packaged by SlackBuilds.org.
+.sp
+[\fIquickload\-file\fP] can be a cartridge ROM image (\fB*.rom\fP or \fB*.ccc\fP)
+or a binary executable (\fB*.bin\fP). If the file exists, it will be
+loaded into the emulator at startup and executed. The filename
+extensions are required, although they are case\-insensitive.
+.sp
+There are no other command\-line options.
+.SH KEYBOARD
+.sp
+The keyboard is laid out like the CoCo 3, meaning that e.g. the
+double\-quote is \fIShift\-2\fP\&.
+.sp
+While \fBovcc\fP is running, press \fIF12\fP for a list of keyboard commands.
+.SH DISK IMAGES
+.sp
+To use a disk image (\fB*.dsk\fP), first connect the floppy drive:
+select \fICartridge\fP \-> \fILoad Cart\fP \-> \fBlibfd502.so\fP\&. After doing
+this, the \fICartridge\fP menu will now have entries for 4 drives. Select
+\fIFD\-502 Drive 0\fP \-> \fIInsert\fP, then use the file selector to navigate
+to the disk image. If necessary, you can choose \fIFile\fP \-> \fIHard Reset\fP
+or press \fIF9\fP to reboot the Coco 3.
+.sp
+Note that it\(aqs easier to move or symlink the disk images into the
+\fB~/.ovcc\fP directory, since this is the default location for the file
+selector.
+.sp
+All the inserted media are remembered in the config file, so when
+you exit and re\-run \fBovcc\fP, the devices and disks will still be
+connected and loaded.
+.SH FILES
+.INDENT 0.0
+.TP
+.B /usr/games/ovcc
+Shell script wrapper, which sets up the per\-user working directory if
+needed, \fBchdir\fPs to it, and executes the real executable.
+.TP
+.B /usr/libexec/ovcc/ovcc
+The actual executable. Normally you don\(aqt want to call this directly.
+Since \fBovcc\fP was ported from Windows, it expects to find its config
+files, ROMs, and loadable modules in the directory it was launched from.
+.TP
+.B ~/.ovcc
+Per\-user working directory for \fBovcc\fP\&. If this dir doesn\(aqt exist, the
+\fBovcc\fP wrapper script will create it. Contents:
+.INDENT 7.0
+.TP
+.B Vcc.ini
+The config file. Human\-readable and (if you\(aqre careful), editable. However,
+the primary way to change the settings here is to use the graphical user
+interface. Any changes made there will be written to this file.
+.TP
+.B Vcc.ini_bck
+Backup of the config file, created whenever \fBovcc\fP is about to overwrite the
+config.
+.TP
+.B lib*.so
+Loadable modules which emulate various hardware that can be attached to the
+CoCo 3. In the GUI, you load these from the Cartridge menu. The standard
+floppy disk module is \fBlibfd502.so\fP\&. These are symlinks to the real files
+in the package.
+.sp
+For a description of each emulated device, see:
+.sp
+\fI\%https://raw.githubusercontent.com/VCCE/VCC/main/README.md\fP
+.TP
+.B *.rom
+ROM images.
+.sp
+\fBcoco3.rom\fP is automatically loaded when the emulator starts up.
+.sp
+\fBdisk11.rom\fP is loaded when the \fBlibfd502.so\fP module is loaded.
+.sp
+Other modules may require other ROM images (not included in the SBo package).

+TRS-80 CoCo 3 emulator
+----------------------

+
+SYNOPSIS
+========
+
+**ovcc** [*quickload-file*]
+
+DESCRIPTION
+===========
+
+**ovcc** is "the portable and open Virtual Color Computer", an emulator
+for the TRS-80 Color Computer 3.
+
+This man page documents **ovcc** as packaged by SlackBuilds.org.
+
+[*quickload-file*] can be a cartridge ROM image (**\*.rom** or **\*.ccc**)
+or a binary executable (**\*.bin**). If the file exists, it will be
+loaded into the emulator at startup and executed. The filename
+extensions are required, although they are case-insensitive.
+
+There are no other command-line options.
+
+KEYBOARD
+========
+
+The keyboard is laid out like the CoCo 3, meaning that e.g. the
+double-quote is *Shift-2*.
+
+While **ovcc** is running, press *F12* for a list of keyboard commands.
+
+DISK IMAGES
+===========
+
+To use a disk image (**\*.dsk**), first connect the floppy drive:
+select *Cartridge* -> *Load Cart* -> **libfd502.so**. After doing
+this, the *Cartridge* menu will now have entries for 4 drives. Select
+*FD-502 Drive 0* -> *Insert*, then use the file selector to navigate
+to the disk image. If necessary, you can choose *File* -> *Hard Reset*
+or press *F9* to reboot the Coco 3.
+
+Note that it's easier to move or symlink the disk images into the
+**~/.ovcc** directory, since this is the default location for the file
+selector.
+
+All the inserted media are remembered in the config file, so when
+you exit and re-run **ovcc**, the devices and disks will still be
+connected and loaded.
+
+FILES
+=====
+
+/usr/games/ovcc
+  Shell script wrapper, which sets up the per-user working directory if
+  needed, **chdir**\s to it, and executes the real executable.
+
+/usr/libexec/ovcc/ovcc
+  The actual executable. Normally you don't want to call this directly.
+  Since **ovcc** was ported from Windows, it expects to find its config
+  files, ROMs, and loadable modules in the directory it was launched from.
+
+~/.ovcc
+  Per-user working directory for **ovcc**. If this dir doesn't exist, the
+  **ovcc** wrapper script will create it. Contents:
+
+  Vcc.ini
+    The config file. Human-readable and (if you're careful), editable. However,
+    the primary way to change the settings here is to use the graphical user
+    interface. Any changes made there will be written to this file.
+
+  Vcc.ini_bck
+    Backup of the config file, created whenever **ovcc** is about to overwrite the
+    config.
+
+  lib\*.so
+    Loadable modules which emulate various hardware that can be attached to the
+    CoCo 3. In the GUI, you load these from the Cartridge menu. The standard
+    floppy disk module is **libfd502.so**. These are symlinks to the real files
+    in the package.
+
+    For a description of each emulated device, see:
+
+    https://raw.githubusercontent.com/VCCE/VCC/main/README.md
+
+  \*.rom
+    ROM images.
+
+    **coco3.rom** is automatically loaded when the emulator starts up.
+
+    **disk11.rom** is loaded when the **libfd502.so** module is loaded.
+
+    Other modules may require other ROM images (not included in the SBo package).

+# 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.
