-diskdefs \- CP/M disk and file system format definitions

-.SH DESCRIPTION \"{{{
-The diskdefs file contains CP/M format descriptions,
-because CP/M in general does not store those in the file system and there are
-no standards of any kind.
-.PP
-A diskdefs file consists of one or more entries of the format:
-.PP
-.nf
-.RS
-\fBdiskdef\fP \fIname\fP
- \fBseclen\fP \fIsize\fP
- \fBtracks\fP \fIcount\fP
- \fBsectrk\fP \fIcount\fP
- \fBblocksize\fP \fIsize\fP
- \fBmaxdir\fP \fIcount\fP
- [\fBdirblks\fP \fIcount\fP]

-\fBskew\fP and \fBskewtab\fP must only be used exclusively.
-.PP
-Comments are marked with a leading hash or semicolon and extend to the
-end of the line.
-.PP
-It is possible to reserve space after the directory beyond \fBmaxdir\fP
-using an inflated DPB ALV0. If the format makes use of that,
-\fBdirblks\fP must be set.
-.PP
-\fBbootsec\fP contains the total number of sectors used by the boot area.
-This is for CP/M systems that map multiple logical tracks onto a physical
-track. While raw disk images can be configured for doing the same,
-accessing libdsk images needs to be done by physical tracks.
