+Projects list file format
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Instead of having gitweb find repositories by scanning filesystem starting
+from $projectroot (or $projects_list, if it points to directory), you can
+provide list of projects by setting $projects_list to a text file with list
+of projects (and some additional info).  This file uses the following
+format:
+
+One record (for project / repository) per line, whitespace separated fields;
+does not support (at least for now) lines continuation (newline escaping).
+Leading and trailing whitespace are ignored, any run of whitespace can be
+used as field separator (rules for Perl's "split(' ', $line)").  Keyed by
+the first field, which is project name, i.e. path to repository GIT_DIR
+relative to $projectroot.  Fields use modified URI encoding, defined in
+RFC 3986, section 2.1 (Percent-Encoding), or rather "Query string encoding"
+(see http://en.wikipedia.org/wiki/Query_string#URL_encoding), the difference
+being that SP (' ') can be encoded as '+' (and therefore '+' has to be also
+percent-encoded).  Reserved characters are: '%' (used for encoding), '+'
+(can be used to encode SPACE), all whitespace characters as defined in Perl,
+including SP, TAB and LF, (used to separate fields in a record).
+
+Currently list of fields is
+ * <repository path>  - path to repository GIT_DIR, relative to $projectroot
+ * <repository owner> - displayed as repository owner, preferably full name,
+                        or email, or both
+
+You can additionally use $projects_list file to limit which repositories
+are visible, and together with $strict_export to limit access to
+repositories (see "Gitweb repositories" section in gitweb/INSTALL).
