.SH Name
gromox\-eml2mbox \(em Utility for converting RFC5322 Internet Mail messages
into a RFC4155 mbox-format mailbox
.SH Synopsis
\fBgromox\-eml2mbox\fP [\fIfile\fP...] \fB>\fP\fIout.mbox\fP
.SH Description
gromox\-eml2mbox reads one or more RFC5322-formated e-mail messages and
re-exports them as a Unix mbox to stdout. The purpose is to make messages
openable with command-line MUAs such as Alpine <https://alpineapp.email/>.
.SH Examples
.PP
When \fB\-\fP is given as an argument, standard input is expected to
contain a \fBlist of filenames\fP (i.e. indirection). This can help
when *.eml leads to an expansion the system cannot handle:
.PP
.RS 4
.nf
gromox\-eml2mbox *.eml >all.mbox
.fi
.RE
.PP
May result in a "Argument list too long" error in sh. Remedy for that:
.PP
.RS 4
.nf
find . \-maxdepth 1 \-type f \-name "*.eml" | gromox\-eml2mbox \-
>all.mbox
.fi
.RE
.PP
To convert a single message coming from elsewhere via pipe:
.PP
.RS 4
.nf
stuff | gromox\-exm2eml >1.mbox
.fi
