For that you would need editing file / editing contents action, but
this is explicitely excluded in current version of Pavan's proposal :-(

It would require using 'git hash-object -t blob -w --stdin' (from body
submitted via POST from textarea) plus 'git update-index --cacheinfo'.
There is however complication that you would need to do open2/open3
because git-hash-object would require bidirectional communication unless
you would use temporary file (command_bidi_pipe in Git.pm, untested).

Let's check what gitweb/INSTALL says currently

        $ make prefix=/usr gitweb             ;# as yourself
        # cp gitweb/git* /var/www/cgi-bin/    ;# as root

WTF with 'gitweb/git*' glob?  

Ah, later there is "Build example", which is

 - To install gitweb to /var/www/cgi-bin/gitweb/ when git wrapper
   is installed at /usr/local/bin/git and the repositories (projects)
   we want to display are under /home/local/scm, you can do

        make GITWEB_PROJECTROOT="/home/local/scm" \
             GITWEB_JS="/gitweb/gitweb.js" \
             GITWEB_CSS="/gitweb/gitweb.css" \
             GITWEB_LOGO="/gitweb/git-logo.png" \
             GITWEB_FAVICON="/gitweb/git-favicon.png" \
             bindir=/usr/local/bin \
             gitweb

        cp -fv ~/git/gitweb/gitweb.{cgi,js,css} \
               ~/git/gitweb/git-{favicon,logo}.png \
             /var/www/cgi-bin/gitweb/

WTF with '~/git/gitweb'... ehh, that one is mine, I guess...


So additional step would be

        cp -fvR gitweb/lib /var/www/cgi-bin/    ;# as root


I hope that we could make installing gitweb as easy as

        make webscriptdir=/var/www/cgi-bin/ \
             gitweb-install
 
or in more complicated case (gitweb modules not installed in cgi-bin)

        make webscriptdir=/var/www/cgi-bin/gitweb \
             GITWEB_BASE="/gitweb/" \
             GITWEBPERLLIB=/usr/local/lib/perl5 \
             gitweb-install

or something like that (I do not know any standard for the name of build
configuration variable which tells where to install web aplication; 
do you?)

Well, I would perhaps start simply with 

  gitweb.perl
  lib/Gitweb.pm

We can modify file organization later; what's important is the build
infrastructure (even if it is instruction in gitweb/INSTALL).
