Subsections

`rcscat`

Concatenate two RCS version files.

Synopsis

rcscat rcsfile rcsarkv

Description

rcscat is a special-purpose utility which concatenates the archived RCS version file to the current RCS version file for an AIPS++ source. It is used by exhale (p

) to update the AIPS++ RCS archive when creating a new base release.

The first file argument specifies the master RCS file which exhale (p) has just ``upreved'' to the new base release, m.0. It contains all revisions from l.0 to m.0, where l = m - 1.

The second file argument specifies the archive RCS version file which contains all revisions from 1.0 to l.0.

The concatenated RCS version file which rcscat writes to stdout contains all revisions from 1.0 to m.0. exhale (p) makes this the new archive RCS file.

Options

None.

Notes

rcscat is not intended for general use.
The process of producing a new base release is described in detail in the entry for exhale (p).
rcscat is implemented as a C program. It manipulates the internal contents of the RCS version files, relying on the fact that revision l.0 is identical to the preceding revision.
rcscat can handle binary as well as plain-text sources.

Diagnostics

Status return values
0: success
1: usage error
2: file access error
3: RCS file format error
