.sh NAME
mkpt - make prototype file for use by mkfs
.sh SYNOPSIS
.bd /etc/mkpt
spec
proto
.sh DESCRIPTION
.it Mkpt
constructs a prototype file
.it proto
according to the directions found
in the specification file
.it spec.
The specification file must contain the name of the  boot file
as the first token, the size of the file system to be created
as the second token and the size of the i-list in blocks
as the third token.
The next set of tokens comprise the specification for 
the root file.
See
.it mkfs
(VIII) for the correct format of the above tokens.
.s3
All of the following tokens consist of directory names.
Directory names followed by a ':' are made directory entries
in the
.it proto
file.
Directory names not terminated by a ':'
are scanned by
.it mkpt
and all entries are put in the
.it proto
file (recursively).
If no ':' terminated directory name
appears, all entries taken from the
specified directories are entered into the
.it proto
file as originating from the root directory.
A directory name terminated by a ':' and
followed immediately by another directory name terminated by a ':'
will be entered as an empty directory entry
in the
.it proto
file.
A directory name terminated by a ':' may be
followed by as many directory names not
terminated by ':'s as desired.
.s3
A directory name terminated by a ':' may be several levels deep,
e.g. usr/usra: .
All subsequent directory names terminated by ':'
will be put in the directory 'usr' .
One may back up a directory level
by means of the entry '..:' .
This enables one to extract selectively
certain sub-directories of a given directory.
.s3
Editing of the
.it proto
file will only be required if
one wishes to change the names of some files.
Otherwise the
.it proto
file may be used exactly as is to create
a new file system using
.it mkfs
(see
.it mkfs
(VIII)).

There are diagnostics for non-existent or non-readable
directories.
.sh BUGS
If a very large
.it proto
file is created, it cannot be
edited to make any changes.
