+Beyond that, there is a long list of Perl modules required, starting with:
+
+* Digest::SHA typically installed with Perl
+ rpm: perl-Digest-SHA
+
+* Email::MIME deb: libemail-mime-perl
+ pkg: p5-Email-MIME
+ rpm: perl-Email-MIME

+ (for HTML/Atom generation)
+
+Where "deb" indicates package names for Debian-derived distributions,
+"pkg" is for the FreeBSD package (maybe other common BSDs, too), and
+"rpm" is for RPM-based distributions (only known to work on Fedora).
+
+Numerous optional modules are likely to be useful as well:
+
+* Plack deb: libplack-perl
+ pkg: p5-Plack

+ (for HTML/Atom generation)
+
+- DBD::SQLite deb: libdbd-sqlite3-perl

+ pkg: xapian-core

+ (optional, for public-inbox-compact(1))
+
+The following modules are typically pulled in by dependencies listed
+above, so there is no need to explicitly install them:

+
+standard MakeMaker installation (Perl)
+--------------------------------------
+
+To use MakeMaker, you need to ensure ExtUtils::MakeMaker is available.
+This is typically installed with Perl, but RPM-based systems will likely
+need to install the `perl-ExtUtils-MakeMaker' package.
+
+Once the dependencies are installed, you should be able to build and
+install the system (into /usr/local) with:
+
+ perl Makefile.PL
+ make
+ make test
+ make install # root permissions may be needed
